Principles Of Management Nokia Marketing Essay

Principles Of Management Nokia Marketing Essay When Nokia phones were first introduced, they needed a lot of promoting and advertising because they were not recognized enough to sell based on their quality and offers to their consumers, so this is where Nokia spent the biggest quantity of money promoting their goods and establishing their brand as a leader in the communications market. These refer to government policies, regulations and legal issues in the country of operation. For example, employment laws, taxation policy and government stability. Political decisions can impact on many important areas for business such as the education of the workforce, the nation health and the quality of the economy infrastructure such as the road and rail system. Legal constraints, such as 3G, must be considered because many businesses plan to make a profit so they may be tempted to misinform their customers about pricing, products quality and the availability of their goods. Also, they may try to cut expenses by using lower quality materials in their products, such as weaker resources for Nokia cases and batteries. Also some companies may set out their waste in ways that harm the environment without ensuring high standards of hygiene and safety in the workplace. Including, outlet stores, which are illegal and can cause legal problems for companies. In 2000, the UK Government started to accept bids from thirteen companies who wanted to run a licence to sell next-generation mobile phones. It raised  £22.47, a neat sum to anybody. Some businesses see profits as more valuable than a strong ethical code and this can run behavior and business conduct. Some unethical practices are illegal and companies can not become involved in them. However there are also some practices that are legal by law but are considered highly unethical by the consuming public. Companies who take on in these practices can lose a lot of market share if they are caught. For example, cosmetic testing on animals is legal, but some of the general public arent happy about it and boycott. Because of this companies, companies must be very cautious about how they conduct themselves. In the communications market, technology is most probably the most important factor that companies like Nokia have to take into account. They must keep up to date with all the newest technological advances, such as camera and video phones, if they intend to obtain the biggest market share and keep ahead of their competitors, such as Sony and Panasonic.

Review of Binding Updates Security in MIPv6

Review of Binding Updates Security in MIPv6 Avishek Dutta   Vikram Raju R. Abstract— Mobile Nodes (MN) in Mobile IPv6 (MIPv6) are given the opportunity to eliminate triangle routing that is inefficient with their own corresponding node (CN) using Route Optimization (RO). This greatly improves the performance of the network. Unfortunately, using this method allows several security vulnerabilities to manifest itself with the MIPv6. Among those, common issues are those concerns the verification of authenticity and authorization of Binding Updates during the process of RO. These types of unauthenticated and unauthorized BUs are the key to various types of malicious attacks. Since it is expected that MIPv6 will be supported by IPv6, several mechanism to ensure BU security will be crucial in the next generation Internet. This article focuses on Mobile IPv6 and security considerations. Keywords/Index Term—IKE, Mobile IPv6, Network Security, Potential threats in MIPv6 I. Introduction The way MIPv6 operates can be seen in Figure 1 [1], with 3 node types, namely the Home Agent (HA), Mobile Node (MN) and the Corresponding Node (CN) [2], while MN’s mobility is detected by a router advertisement message including an MN able to make a router send its advertisement message by request, if needed. Following mobility detection, the MN gets a CoA unlike in MIPv4, after which it sends the BU message to the HA and the communicated corresponding node (a node wishing to connect to, or is communicating with MN). The HA and corresponding node update the binding list and send acknowledgement messages [1], meaning that the Mobile IPv6 allows an MN to alter its attachment point to the internet while maintaining established communications [3]. This paper presents an analysis of both Route Optimisation (RO) and Identity Based Encryption (IBE) protocol with proposal to strengthen the level of security of a BU method. This method uses the public key to create an authentication th at is stronger. II. MN-HA Authentication Mutual authentication between an MN and its HA is mandatory in MIPv6, and usually performed with IPSec and IKE, while session key generation and authentication are done with IKE. Using X.509 certificates in IKE is the existing method of performing these tasks. The MN moves to a foreign network and obtains a new CoA. MN carries out a BU on its HA (where the new CoA is registered). HA sends a binding acknowledgement to MN. A Correspondent Node (CN) tries to contact MN, with HA intercepting packets destined to MN. Next, HA tunnels all packets from CN to MN using MNs CoA. When MN replies to the CN, it may use its current CoA (and bind to the CN) and communicate with the CN directly (â€Å"route optimization†), or it could tunnel all its packets through the HA. Sometimes MN and HA share a common secret, possibly occurring in WLAN instances when MN shifts to another WLAN which requires authentication [4]. If there are no shared secrets, extending the IKEv2 authentication process to identity-based authentication as opposed to X.509-based authentication certificates is usual. It can also be assumed that both MN and HA use the same PKG, and according to the relationship between these three entities, any trust level from I to III may be applied during private key delivery. Regarding IKE, two main methods of implementing IBE exist, the first of which involves modifying IKE’s four-way handshake while the second utilizes EAP to generate a new IBE-based EAP authentication method [4]. A. Modifying IKE IKE could implement IBE through the addition of a third authentication method, other than the previous shared secret and X.509 authentication. Instead of X.509 certificates, IKE also uses â€Å"IBE certificates†. IBE-based authentication functions fundamentally the same as X.509 authentication, in that to authenticate peers the same information block should be signed as in the X.509-based authentication, in addition to a signature based on IBE (i.e. the Hess signature). Currently, identities are replacing certificates and revocation lists do not need to be checked. Ehmke (2007) implemented a prototype which can realize this idea. Performance wise, clearly transmit certificates or certificate requests are no longer necessary since the IKE identity can be used straight as the public key for authentication. Also, expensive certificate-chain checking is redundant while elliptic curve cryptography-based hardware- accelerated IBE algorithms are sometimes quite efficient, particularl y in embedded devices [4]. B. Extensible Authentication Protocol Several wireless networks utilize the Extensible Authentication Protocol (EAP) [5] for access authentication. EAP techniques commonly deal with AAA servers which affect the required authentications, after which notifications are relayed back to a functional module (Network Access Server) in the access network. For Mobile IPv6 [6], the Binding Authentication Data option [7] helps enable different authentication techniques, while a subtype exists for AAA- based authentication like EAP. On the other hand, there still are EAP methods requiring extra handling and specifications which present Binding Authentication Data option documentation does not provide. Currently, specification from this document is for at least some very widely deployed EAP methods, so, often, when EAP is needed, Mobile IPv6 tunnel redirection to a wireless device’s new CoA can be done much faster [8-10]. C. Using Extensible Authentication Protocol Figure 2 illustrates possible steps in EAP implementation. It is advisable to use EAP as part when establishing a concurrent shared key to be used in the final two message exchanges leading to authentication [4]. Chen and Kudla’s key agreement with IBE technique is one alternative protocol (protocol 2’ in [11]) that can function in the absence of a key escrow, so CERTREQ and CERT messages in steps 2, 3, 4 are not necessary (Figure. 2). Figure 3 illustrates the resulting IKE Initial Message exchange. 1. I _ R: HDR, SAi1, KEi, Ni 2. R _ I: HDR, SAr1, KEr, Nr, [CERTREQ] 3. I _ R: HDR, ESK{IDi,[CERTREQ,][IDr,]SAi2,TSi,TSr} 4.

IKE Initial Message Exchange: Authentication using EAP [12]. Here, the same PKG is shared by MN and HA, where P is a public PKG parameter, and HA and MN choose the random numbers a and b, respectively. The Chen-Kudla protocol produces a session key solely for message 7 and 8 authentication. The AUTH payloads have to authenticate messages 3 and 4 based on MAC and a secret key generated by an EAP protocol [11]. 1. MN _ HA: HDR, SAMN1, KEMN, NMN 2. HA _ MN: HDR, SAHA1, KEHA, NHA 3. MN _ HA: HDR, ESK{IDMN,[IDHA,]SAMN2,TSMN,TSHA} 4. HA _ MN: HDR, ESK{IDHA,AUTH,EAP_CK_Req(a ·P,a ·QHA)} 5. MN _ HA: HDR, ESK{EAP_CK_Res(b ·P,b ·QMN)} 6. HA _ MN: HDR, ESK{EAP(success)} 7. MN _ HA: HDR, ESK{AUTH} 8. HA _ MN: HDR, ESK{AUTH,SAHA2,TSMN,TSHA} Fig 3. IKE Initial Message Exchange: EAP with IBE Authentication [12]. But since IBE uses PKG, it is almost impossible to guess which MN will be communicated by the CN. We cannot simply assume the same PKG is used by both MN and CN. Multi-PKG is used instead but it is not recommended for larger networks. III. MN-CN Authentication Via the MIPv6 protocol, MN can keep its network connection even when the network attachment modifies [13]. An MN can be reached at its home address (HA) anytime, even when not physically in its home network. When an MN is connected to a foreign network it obtains a CoA from the local router through stateless or stateful autoconfiguration. Next, for home r egistra tion, the MN sends HA its current location information (CoA) in a BU message, then HA can redirect and tunnel packets intended. for the MN’s home address, to the MN’s CoA. When a foreign network MN is in contact with a CN (a stationary or mobile peer communicating with a MN) through the HA, bidirectional tunnelling takes place for instances when CN is not bound to the MN (registration is in progress) or MIPv6 is not supported by CN [4]. If the CN supports MIPv6, a more effective mobile routing technique, Route Optimization (RO), can be used. RO is effective as it provides the most direct, shortest path of transmitting messages between an MN and a CN, eliminating the need for packets to pass through the HA, and avoiding triangular routing (bidirectional tunnelling). Prior to setting up RO, the MN must send CN a BU packet containing its CoA with present location data. On the other hand, security risks with RO [14] can be for example that an MN may send CN a false BU packet and redirect the communication stream to a desired location, resulting in a Denial-of-Service (DoS) attack. Thus, for increased security, it is important to authenticate BUs in RO [4] [15]. What happens between a CN and MN is not the same as between an MN and its HA. Since CN could be any node, MN and CN have no shared secrets or trusted certificates. Thus, Return Routability (RR) can be used, as: †¢ An MN sends CN a home test init (HoTi) and care-of test init (CoTi). HoTi is sent directly through the HA and CoTi. HoTi has the home address and CoTi has the CoA as source addresses, both including a cookie. †¢ Upon receiving either HoTi or CoTi message, CN immediately answers with a home test (HoT) and care- of test (CoT) message which gets sent to the respective source address. Each reply contains the cookie recovered from the nonce indenx, corresponding init message, and a keygen token, later for BU authentication use. When MN receives HoT and CoT, RR is done. Only MN can receive packets sent to both its HA and CoA, and can now hash the two tokens to calculate the binding key. This key is utilized for generating a Message Authentication Code (MAC) for BUs, and MAC can be verified by CN. RR provides an analysis of a nodes reach-ability during authentication but do not validate address ownership in IPv6. IV. MIPv6 Security Analysis Providing security against different types of malicious attacks e.g. denial of service (DoS), connection hijacking, man- in-the-middle and impersonation, are the basic objectives for the development of IPv6. The objective of improved security is to create routing changes that are safe against all threats. Threats are based on the routing changes that provides mobility in the network. Threats faced by Mobile IPv6 security can be divided into different categories: __ Binding update (BU) to HA type threats __ Route Optimisation to CN type threats __ Threats that attack the tunnelling process between HA and MN __ Threats that uses Mobile IPv6 routing header to return traffic of other nodes Binding update and route optimisation threats are related to authentication of binding messages. Communication between MN and HA needs trust and communication authentication. This is because MN agrees to implement the HA services therefore relationship between the two must first be secure. However, the CN and MN does not have prior relationship but authenticating messages between the two is still possible. For example, this is possible by authenticating the public key. If a malicious packet is sent to the HA using the same source address as the MN, the HA will then forward the packet containing the MNs source address contained in the malicious node. However, this DoS attack can be prevented by using an algorithm to verify the BU message receives by the HA. Such threat can also be avoided when a new routing header is used to replaces the incorrect header that manoeuvres around firewall rules and obtaining a constrained address [16, 17]. V. Proposed Protection of BU Message Corresponding Author: XYZ, [emailprotected] Once the BU message is complete, the MN will receive normal traffic from the CN with the new CoA. The CN with the new nonce sends to the MN a Binding Update Verification (BUV) within a specific time frame e.g. 10 seconds. The MN then needs to reply within 10 seconds otherwise the connection between MN and CN will be terminated. This method minimises any damages caused by bombing attacks where packets are sent to the MN by malicious nodes. Cryptography Generated Address (CGA) can also be use to make spoofing type attacks more harder. Private keys can be use to signed the message as well. Since redirection attacks requires both public and private keys to perform[18-20]. Possible threats and solution is listed in table 1 [4, 17]. VI. Conclusion The requirement for Mobile IPv6 is still not complete considering there are some essential issues that are not addressed. One of the most important issues are protocol security because without secure protection against attacks, the protocol would not be accepted thus will not work at all. Presently, the standard method use for BU protection in transport mode as well as securing the connection for control message sent during home registration method is the Encapsulation Security Payload (ESP). IPSec has several advantages over SSL/TLS which is IPSec can perform without IP restriction, any protocol can be encrypted and also encrypt any packets with just their IP headers. Unfortunately, IPSec needs to be configured with various settings thus making it complicated. The IKE protocol can control the mutual authentication and cryptographic algorithm negotiations as well as dynamic key management. Additionally, authentication method such as shared secret, Extensible Authentication Protocol (EAP) or X.509 certificates can be use to create safe communication between peers.

Bilingual Education: Building Bridges Essay example -- Education

Bilingual education, as an educational program, was initially promoted by educators in the seventies (Hunger of Memory 26) and since then has been a topic of many debates in America. Some argue that bilingual education only serves as a detriment to American culture. Others argue that bilingual education is beneficial to those who come to live in America and want to become a part of the culture, but lack proficiency in the English language. Two authors, who have each taken opposite sides of the debate on bilingual education in America, are: Richard Rodriguez and Ariel Dorfman. Richard Rodriguez believes that bilingual education creates a feeling of separateness between foreign language speakers and American society; therefore, bilingual education delays the formation of a public identity. In contrast, Ariel Dorfman argues that bilingualism in America will be a bridge to better understanding other cultures. I assume the position of being neither, against or entirely in favor of bilingu al education. I am in favor of bilingual education because it can be an effective segue to learning the English language and I believe it is very important to remain connected with our family’s language and culture. However, I also recognize the negative feeling of separateness from the larger public that bilingual education can have on foreign language speaking families, which hinders my ability to fully embrace bilingual education. Ariel Dorfman is an Argentinian author who struggled throughout his life to find a balance between the Spanish and English languages. As a result of Dorfman’s â€Å"bilingual journey† (Heading South 25), he argues that bilingual education is beneficial to American society.

Mutations in the Alpha 1,2-Mannosidase Gene Essay -- Scientific Resear

Introduction Intellectual disability (ID) is defined by the American Association of Intellectual Developmental Disabilities as having â€Å"significant limitations both in intellectual functioning and in adaptive behavior†. [1] Earlier it was believed that behavioral abnormalities, such as Intellectual Disability, were caused by the social or environmental environment in which the individual lived in.[2] However, with the breakthrough of the genetic analysis, it has been shown that more and more of our behavior is influenced, if not controlled, by our genes. [3]This advancement is important for our understanding of ID to expand. ID can occur when there is a mutation on one or more of the genes in the individual’s chromosome set. [3]There are different types of mutations; autosomal mutations (mutations occurring in one or more of the 44 autosomal chromosomes [in humans]), mutations in the sex chromosomes (the two chromosomes that amongst other things determine the individual’s sex), and there are also chromosomal disorders such as nondisjunction in where one of the two homologous chromosomes fails to separate from its sister chromatid during cell division, resulting in an extra chromosome in one daughter cell and one less chromosome in the other.

The Roman Empire and Classical Greece

The Roman Empire and Classical Greece were undeniably two of the greatest societies in history. As far as the political and cultural developments of the two civilizations, the Roman Empire's (approximately the first five centuries of the Common Era) form of government contrasted with that of Classical Greece (approximately 500 B. C. E to 300 B. C. E. ), however the two societies shared similar enthusiasm for literature as well as almost identical religious beliefs.An extremely prominent characteristic of Classical Greece was its decentralized form of government. There, the nation was divided into several polises, or city-states. Each polis had its own government system – which could be a monarchy (the most common), a Tyranny, an Oligarchy, or a Democracy (Athens being the world's first). This is very strange compared to the government of Rome. The Roman Empire was centralized and ruled by one solitary man: the Emperor. Although the senate had some influence of the Roman govern ment, the Emperor held absolute power.Centralization and absolute power was necessary in the large Roman Empire because the vast amount of land being controlled was too much for Rome as a republic to handle. This was not the case in Classical Greece, which was much smaller, and could allow its polises to make their own decisions to keep the people happy. For this reason, we see a difference in the styles of governments of the two societies. Despite this difference though, Classical Greece and The Roman Empire still shared love and support of literature. Several great works of literature came from Classical Greece.During the classical era, many genres of western literature became more prominent. This includes lyrical poetry, odes, pastorals, dramatic presentations of comedy and tragedy, histories, philosophical writings, government writings, and more. Many works from this time became classics in our world today. The Romans also had a strong emphasis on literature and they wrote almos t everything of significance down. It was essential for the Romans to keep extensive written government records on order for them to organize their extremely large empire.Literature was able to strive in both the Roman Empire and Classical Greece because of the emphasis both societies had on education. Without this, neither would have the educated authors, poets, and philosophers needed to produce the great literature that they did. Furthermore, Classical Athens and the Roman Empire shared almost identical religious beliefs. For almost every Greek God, there is a corresponding Roman God. For example, for Zeus there is Jupiter, for Aphrodite there is Venus, Poseidon there is Neptune, and for Hades there is Pluto.The list goes on to include more of the major as well as minor gods, although some gods, such as Apollo, have the same name in each religion. In Rome, despite the change of name, the gods play the same role and have indistinguishable powers to their Greek counterparts. The re ason behind this similarity is that when Rome was developing into a strong civilization, leaders saw the accomplishments of the Greece, especially Athens, and decided to adopt their gods in hopes of reaching the same success.To make them their own, they simply changed the names. Unmistakably similar in their belief systems and love of literature, and at the same time clearly diverse in their forms of government, Classical Greece and the Roman Empire were able to share similarities as well as differences in their cultural and political developments that enabled them to become the prominent and strong civilizations that they did.

Morality of Drug Use

  In his book entitled â€Å"Thinking Critically About Ethical Issues,† Vincent Ryan Ruggiero formulated a criteria consisting of three elements, which criteria relates to respect for persons as a theoretical construct and a practical ethical standard for everyday decision making (Ruggiero, 78). These three criteria are obligations, moral ideals and consequences, which are all applicable to the determination of proper conduct in relation to drug use (Ruggiero, 79).Moral Ideals.Ruggiero explained his concept of moral ideals as distinct from obligations. For him, ideals are goals that characterize excellence, which goals are aimed at by different individuals (Ruggiero, 78). In particular, and in relation to respect for persons, he discussed that moral ideals assist a person in achieving respect for persons (Ruggiero, 80).He also explicated that moral ideals could be composed of various categories, such as the â€Å"cardinal virtues† of old and the theological virtues of religious thinkers. He likewise posited that moral ideals could vary from person to person, or from culture to culture (Ruggiero, 81). This is an important proposition, because the differences in moral ideals determine the differences in treatment given by each person on varying actions. Thus, one person could regard a moral ideal as more than just that, for example as an obligation that requires compliance.Applying this concept to the ethical issue of drug use, it would be concluded that the perspective could be viewed from a number of different perspectives, which also have varying moral ideals. This means that drug use could be viewed positively or negatively by different cultures or population, depending on their respective moral ideals.For example, a population of medical practitioners such as doctors would hold on to the ideal that drug use is necessary in certain cases, such as in situations of a disease or illness that could only be cured by the administration of particular drugs. On the other hand, a population consisting of the religious whose faith dictates the avoidance of drugs would hold on to the exact opposite moral ideal. Thus, an ethical decision hinges on the moral ideals to which the population concerned adhere, because such moral ideals determine the kind of ethical decision that would probably be made in any given situation.Obligations.Ruggiero also discussed the notion of obligations as a criterion for determining respect for persons. His concept of obligations refers to the element of compulsion into doing a certain act, as determined by the situation involved or the relationship between or among parties (Ruggiero, 80). He likewise explained that different kinds of situations and interpersonal relations dictate the kind of obligations that are imposed on a person.Viewing drug use in the light of Ruggiero’s concept of obligations, drug use could be ethically justified by formulating a situation such that the administration or pre scription of medicinal drugs and the corresponding use is seen as an obligation on the part of the doctor and the patient to maintain the latter’s good health and long life.Consequences.Finally, Ruggiero discussed the concept of consequences, which refer to the effects of an action on a person (Ruggiero, 81).   He states that the effects could be classified into beneficial or harmful effects, or grouped according to kind, such as whether they are physical or emotional (Ruggiero, 81).The most important aspect of Ruggiero’s discussion of the topic is his position that the benefit or harm caused by a specific act is determined by the impact of such an act on all persons involved, including the actor (Ruggiero, 81).This criterion is relevant in the issue of drug use, because ultimately, any ethical decision on this matter hinges on its effects on the user. Therefore, drug use could be ethically justified if it is shown that there are health benefits that could favor the user or his community. On the other hand, proof that drug use only leads to individual or collective harm would tilt the favor against drug use.In sum, Ruggiero’s three criteria are relevant in any discussion of the morality of drug use. These criteria provide practical knowledge with regard to the things that one should be looking at, prior to making an ethical decision.Works CitedRuggiero, Vincent Ryan.
