TPM components, TPM keys - Research Paper Example Attestation on the other hand is a verification process of the computer’s trustworthiness and determining if it has been breached or not. Other devices such as network equipment and mobile phones can be computed using TPMs (Trusted Computing Group, 2012). In summary, the TPM has four main functions which include platform monitoring, secure storage, encryption operations and authentication services (Hewitt, 2006). Operations on sensitive data can only take place in special locations, called shielded locations, which must be incorporated in the TPM. It should be impossible for user programs to access these locations. Protected capabilities are the set of commands which one can use to access the shielded locations. This set of commands protect the shielded locations and report integrity measurements at the same time. The TPM has several major components which are illustrated in the following diagram. TPM COMPONENTS The SecureI/O component It is a control component that manages th e TPM’s information flow to the outside and also controls and routes internal signals (Hewitt, p.3). The I/O encodes and decodes the information passing over the internal and external buses (Gunupudi, p.11). The Cryptographic Co-Processor This is a major subdivision of the TPM containing various cryptographic engines. The RSA key generator, RSA encryption/decryption and SHA-1 engine must be included in its functionality (Microsoft 2012). Other asymmetric algorithms such as DSA or elliptic curve, are allowed by the specification. The strength of 2048 bit RSA key should be the threshold of all storage and identity keys as this is enough to offer sufficient protection from malicious access. Digital signatures and encryptions are made using the RSA algorithm. If RSA encryption is not used when a signing is done within the TPM, it stands the risk of being rejected by other TPM devices. The engine must support key sizes ranging from 512,768, 1024 and 2048 bits. The minimum recommen ded size is 2048 bits. The specified public exponent of RSA is (2raised to 16 +1). The SHA-1 engine requires 160-bit keys and provides the primary hash algorithm used by the TPM. The implementations of the HMAC engine are dictated in RFC 2104. It involves turning a keyless hash function in to a keyed hash by incorporating a cryptographic key. This will allow the chip to detect proof of knowledge of Auth Data and also ensure that authorized incoming requests have not been tampered with (Hewitt, p.4). The TPM also uses the symmetric encryption algorithm internally because they cannot have user-accessible interfaces. They are used in encrypting internal data that was fed in to the TPM from an outside source and encrypting authentication exchanges. Other algorithms such as AES are allowed by the specification depending on the sufficiency preference of the implementer (Hewitt, p.5). The Key Generator It’s a protected capability function that manages the generation of keys and nonc e (Gunupudi, p.12). The keys generated are used for encryption.The specification of the key generator is not strict. It however emphasizes that data that has existed in a non-protected location as a key should not be used. The specification also requires that all nonces be from the TPM’s Random Number Generator (Hewitt, p.5). The Random Number Generator It’s the source of entropy in the TPM (Gunupudi, p.12). It consists of a post-processor with a hashing

Eygpt problems Essay Example | Topics and Well Written Essays - 750 words

Eygpt problems - Essay Example Giving the example of Lebanon, Shadid shows just how confused the state of affairs is, where people cannot decide on their own just what exactly they want from their country. Though Shadid concedes that Western powers are to be blamed for merely giving lip-service to the cause of the people while turning a blind eye towards the dictators as long as their interests are looked after by the despotic governments, however, he is quick to point out that the blame does not rest with them alone. The frustration caused has much to do with the failure of the states to satisfy their citizens in giving them a good life. All this, Shadid opines, has left the door open for people’s revolutions, as is evident from what happened in Tunisia and Lebanon and Egypt. This, he contends, marks the beginning of the end of the status quo that has existed in the Arab world. The article is a very well thought out piece of work. It is thought provoking indeed. While those in the West are quick to point o ut at the actions of the leaders of the Arab World and blame them for a lot of human rights abuses, for instance, what we do not realize sitting here is that in some way, our government has to carry the blame for letting these despots come to power and letting them stay in power as long as our interests are served. However, as Shadid pointed out, the state of affairs has been brought to this because of the way the states have been treating their citizens. For far too long the despots of the Arab World have treated their citizens as if they are less than human. Hiding behind the force of their police or armed forces, they sought to create fear in the hearts of their citizens, and they succeeded in doing so too. They ruled with an iron fist and accepted no dissension whatsoever. However, the rules of the game have changed. As is evident from what happened in Tunisia, and what happened in Egypt after this article was written, it is clear that the masses still have the power to bring ab out change in the system. Things have come to the point where even Libya’s Gaddafi is facing a similar demand from his people: he should resign from his tyrannical rule and let someone else rule the country for a change. With all that has been happening in the Arab world, it is clear to see that the politics of the twentieth century will not hold credence. With globalization and the technological advancement in methods of mass communication, it is now next to impossible to hold information from people. It is this free flow of information that has caused people to get together and speak for their rights. It is only a matter of time before this fire spreads throughout the Arab world. It is, therefore, needed that the rulers of the region talk heed of the warning signs and start implementing a more humane and more tolerant policy, both towards the citizens, in general, and their opposition, in particular. However, it can be contended that it might be too late, as now, when peopl e have seen how much the masses can attain by just banding together; they would not be willing to back down and remain obedient servants to their tyrannical rulers. The repression by

Bussiness Ethics Essay Example | Topics and Well Written Essays - 2250 words

Bussiness Ethics - Essay Example Although, some manufacturers made deliveries to IKEA, mostly at night to avoid being seen, IKEA thought of other strategic options to counter this problem, and one among them is outsourcing. This made IKEA to go scouting abroad for manufacturers and Kamprad entered into contracts with number of factories in Poland, thus ‘seeding’ more outsourcing. It was this early decision of Kamprad to seek least expensive alternatives to domestic manufacturing of the products turned out to be a more profitable avenue for IKEA to take. As, this outsourcing strategy reduced the costs of production, it is able to offer affordable or cheap prices to the customer, thereby bringing in more customers. â€Å"IKEA currently works with 1,300 suppliers in 53 countries, but Kamprad made the pioneering decision to source furniture from communist Poland as early as 1961. Since manufacturing costs were 50% lower in Poland than in Sweden, his decision looks brilliant in hindsight.† (Barthelemy 2006). Importantly, IKEA continued as well as extended its outsourcing strategy to other countries particularly 1980’s and 90’s, particularly to Asian countries like India, Ch ina, Pakistan, Philippines, etc, where they can access cheap labour. Although, outsourcing to these countries gave IKEA a cost-effective option, it also led to the rise of ethical issues and controversies, both from the economic as well as political perspectives, thereby making or even forcing IKEA to come up with Corporate Social Responsibility (CSR) based activities. IKEA outsourced to the Asian countries many of its manufacturing processes including making of carpet, rugs, wicker baskets, etc. That is, in starting from 1970s and more prominently from 1990’s, they found many local manufacturers cum suppliers, who would manufacture the products and supply to them with IKEA label. This turned out to be a productive and profitable option, as IKEA was able to get good productivity for cheaper prices, when compared to the

Marketing - Essay Example Now the organization chosen to accomplish the study is McDonalds. In the external analysis the report will also shed light on the factors such as demographics, customers and also the cultural aspect. In the internal analysis section the study will emphasize on the missions and goals of McDonalds, its past marketing activities, human resources and research and development among the others. Furthermore the report will mainly try to uncover the strengths, opportunities, weaknesses and threats of the company. This will be accomplished with the help of a SWOT analysis. McDonalds Australia: A Brief Overview In the Australian context, the first outlet of the company was opened in the suburbs of Sydney which was known as Yagoona. With the course of time the company has been able to establish 780 stores and employs around 85,000 people across Australia. McDonalds Australia is not a listed company and is privately limited. It is basically a franchisee based venture where the restaurants are mo stly owned and opera rated by individual businessman (McDonalds, n.d.). Industry Analysis McDonalds is a retail food chain restaurant and it belongs to the fast food industry. Hence in order to analyze the industry Porter’s 5 forces model has been used. The analysis is presented below:- Porter’s 5 forces 1. Threat of new Entrants New entrants are described as the companies that are presently not competing within the given industry but has the potential to compete in the industry if chooses to do so. The start up of cost for such kind of business is low and there is easy access to the markets. Furthermore owing to the fact that Australia is politically stable and offers much favourable condition, the threat of a new entrant in this industry is high. 2. Threat of substitutes products Substitute products are characterized by the availability of same category products, which performs the same function as the existing product (DePamphilis, 2011, p.143). McDonalds is special ized in serving various types of Burgers to the customers. Nevertheless in this aspect there are many substitute products such as Pizzas, Sandwiches and other fast foods. Hence the threat of substitutes is also high. 3. Bargaining power of buyers The bargaining power of the buyer refers to the capability of consumers to bargain and lessen the price of the commodity or to increase the cost of the company by demanding more quality products and services (Hill and Jones, 2012, p.58). Bargaining power depends on how quickly the buyer identifies other sources. In this context there are not many established players like McDonalds, KFC and Subway among others. Hence the bargaining power of buyers is low. 4. Bargaining Power of Suppliers Suppliers are also other organizations which provide raw materials, service to the host organization. The bargaining power refers to the capability of the suppliers to increase the price of the raw materials or to decrease the quality of goods and service wi th the supply of substandard quality materials for low price. There are large numbers of suppliers of raw items for fast food industr

Advice on Advancing Funds against Military Retirees Pensions Case Study

Advice on Advancing Funds against Military Retirees Pensions - Case Study Example Unconscionability is a legal principle in contract law relating to conditions which are so much unfair or substantially skewed to benefit the party with greater bargaining power. As such, the contracts made therefrom negate the values of good conscience in the contract. Generally, an unconscionable agreement is considered to be invalid because the disadvantaged party would not have agreed to it under reasonable circumstances. As such, the party with greater bargaining power is not usually permitted by courts to enjoy the benefit(s) because the contract lacks sufficient consideration by the other party for a fair share of the risks and benefits. Unconscionable contracts are determined by assessing the conditions of the contractors when the agreement was made, such as each party’s knowledge or mental competence, age, and bargaining power. Other equally vital factors are; lack of options and acts of inducement. Wasik noted that unconscionable behavior is also occasioned by misrepresentation of fact and fraud, especially where intentional distortion of fact results in the loss of a valuable asset. When an individual or party benefits from a contract to the detriment of another, the perpetrator may be liable for criminal fraud or deceit in a civil action. In Universal Grading Service v. eBay, Inc., 2009 U.S., eBay’s actions of influencing the value of the coin in its online auction processes were found to be conscionable because it was not fraudulent. In this case, the test for unconscionability will depend on whether the military retirees had the ability to match the Client’s when they were forming the contract.
