Physical Tamper-Resistant Devices - Essay Example In this scenario, encryption keys are stored in a computer that can be vulnerable to abuse, use, or alter by an illegal user or an attacker. For various reasons one of the most important techniques to secure encryption keys is to store them in a more protected tamper resistant hardware system. These systems can be utilized for a wide variety of applications varying from protected online cash transfer to e-mail and credit card transactions. In fact, they provide physical safety to the encryption keys saved inside them, as a result making sure that these security keys have not been illegally modified or read. Naturally, attaining access to the information and data on tamper resistant device necessitates knowledge of a password (or PIN) that exactly what kind of system access can be attained using this information and data depends on the device (EMC Corporation., 2012; Anderson & Kuhn, 2000). There are different types of physical tamper-resistant devices and each device has different ch aracteristics. Basically, physical tamper-resistant devices are based on some kind of seals, locks, covers, coatings, and tamper response and detection mechanisms. According to FIPS 140 security levels there are basically four levels of physical security management standards. For the sake of application of a physical tamper-resistant system, the level 1 is about the implementation of some primary requirements on cryptographic algorithms. In this scenario, there are no such physical security devices at this level. The level 2 of the physical tamper-resistant system is based on the tamper evident seals or coating. While at level 3 we have an improved physical security system that can stop illegal access to systems and devices. The level 4 is based on extremely dependable tamper detection and response devices that can instantly erase the entire secret data (Anderson & Kuhn, 2000; NIST, 2001). In addition, the physical tamper-resistant can be of different types for example for the sake of devices’ warranties and support management we have tamper evident seals. These seals can deal with a tempering of opening devices. Such seals are used to make sure that warranties and support services still be offered (ommerling & Kuhn, 1999). In addition, for the sake of technology based systems security management we make use of the tamper resistant microprocessors. Such microprocessors are utilized to store as well as process sensitive and private data and information. To stop security breaches and attacks from illegal source such chips make it difficult for the outsiders to get access to sources as well as make sure that these resources are accessed only by the embedded software. Another kind of tamper resistance devices is known as DRM. These devices can include set-top boxes, smart cards and other technology based systems which are utilized for the management of digital rights. Additionally, some software applications are also used for tamper resistance. However, the se systems are not similar to above discussed physical devices but have embedded instructions to lock the system after a specific number of illegal attempts or destroy the data as well (Anderson & Kuhn, 1997; ommerling & Kuhn, 1999). According to my point of view tamper resistant systems are similar to bank vaults. Such kinds of system are characterized through the outer device case design for solid access management scheme. Someone needs high level methods and tools to breach such security based system. However, some of the systems are tamper responding systems which are based on the idea of the burglar alarm method. Such kind of security mechanism is based on detection of some illegal activity or intrusion and notifying the responsible staff for such issues.

Stuff about the bomb Essay examples -- essays research papers

The Most Difficult Decision Ever President Truman stood in the oval office full of many advisors, but was truly alone ready to make the hardest decision, which would change the world forever. Is dropping the bomb the right decision for the president to make? Dropping the bomb wasn't the right decision to make, because many people lost their lives and it wasn't right to make that move. On December 7, 1941 the Japanese bombed Pearl Harbor and on December 8, 1941 the president of the United States asked the congress to declare war on Japan. That’s what made the United States enter the war. When they attacked at that day, the Japanese destroyed 5 battle ships and another 19 ships. The United States kept fighting with Japan until 1945 and many Americans lost their lives while fighting for the different islands. The military leaders in America knew that this fighting will be for a long time and there will be more death, so they start striking them with long-range B-29 bombs. They even stroked on the Japanese main land in Tokyo March 1945. The president Truman was informed from the physicist J. Robert Oppenheimer and other scientists that the atomic bomb was ready to be use. First of all, Truman and his secretary of war Stimson thought it was better to use the atomic bomb to end the war quickly, and to stop the soldiers and people from getting killed. Truman got advises from many American military leaders. They told him that it would be better if he uses it on the Japanese main l...

Children: a Good Target Market or an Abuse of Innocence?

Children: A Good Target Market or An Abuse of Innocence? Advertising is a way many businesses attract consumers. Consumers are, after all, their source of income. Billions of dollars are spent every year by corporations to huge advertising companies to think of the next big commodity. However, the most attractive target market today is children, which inevitably sparks controversy throughout the country. When discussing advertising to children, one should highly consider how the effects the products being advertised pose to children, the status of our countries laws, and the current uses of child advertising and the effect they may have on their audience because we need to think of the children first in order to protect our country’s youth. Many businesses have made the arguable decision in marketing towards children. If the venture is done the right way, it can be a successful form of getting attention to a business. In the article â€Å"Brand loyalty starts from a very early age,† Lou Cooper reveals, â€Å"Influencing children at a young age could see them retain their custom in the future† (24). However, if done incorrectly or unethically, youth advertising can be very dangerous and influential to a child in the wrong way. More and more manufacturers  and television advertisers  think that children constitute an important group for their target  market. They see other businesses succeeding when they use the tactic and they believe they need to use it too so as to remain competitive in the industry. However,  television advertising  aimed at children is extremely harmful to child development. Over the last few decades,  television advertising  has changed people's life styles and buying habits, especially children. Children have larger spending power. With the additional reassurance from statistics and research, more and more manufacturers and  advertisers  think that a young age group is an important group for their target  market. However,  television advertising  aimed at children is extremely harmful to child development because of the many harmful and unhealthy things the television is portraying as acceptable and even going so far as to making a harmful product sound attractive and necessary to a young consumer. Television aids the alcohol industry, as well as the fast food industry in spreading the word of their harmful products. The fast food industry is especially taking advantage of their marketing ability, and consumers are paying the price for it, with their health. According to the film Super Size Me, over the past few years, there has been a doubling of childhood and adult diabetes. Also, in the film Super Size Me, Morgan Spurlock provides the information that more children are having liver abnormalities and are already showing signs of cirrhosis, a clinical scaring of the liver. As stunningly accurate as in Fast Food Nation, Eric Schlosser mentions, â€Å"But the value meals, two-for-one deals, and free refills of soda give a distorted sense of how much fast food actually costs. The real price never appears on the menu† (9). Thus, the harmful products shown on TV should be highly monitored and perhaps even forced laws upon certain ads to protect the public. The founding laws of our nation have worked for us for centuries. They protect us when is necessary and allow us freedoms when appropriate. Legislators have been able to protect us very well with the constant updating of our laws. Through amendments and many new laws, law makers have been able to stay current with issues at hand. However, because our country’s laws haven’t taken another modern twist, many children are feeling the consequences. As seen in The United States Bill of Rights, the first amendment to the Constitution is â€Å"Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press† (US Const. , amd. 1) When creating the law, however, legislators in the revolutionary time period surely didn’t suspect that the safety of children would be at stake when they wrote such a broad and vague concept. The legislation for advertising to children is minimal, and most advertising companies have free reign to do whatever they want. When a commercial is geared toward children, they find it appealing and some almost comforting. Fast Food Nation’s Eric Schlosser expressed that children are exposed to â€Å"30,000 commercials a year. † Congress has passed laws in the past about setting regulations for the advertising of cigarettes and alternative means of marketing because of their extremely harmful and negative side effects they threaten consumers with. Certain means of advertising in movie theaters was reviewed and banned; Truthful advertisements are being forced on to cigarette companies. Advertisements in movie theaters would show pictures of a random place and quickly show a flash of a product so people in the audience would need to have it. For example, they would show a large desert and then quickly show a Coke, and a person sitting in the audience would stand up and need to buy the Coke, almost as if they were brainwashed. Cigarette companies are now forced to put pictures of diseased organs on the box of cigarettes so as to warn the public of their unhealthy and dangerous aftermath and hopefully thwart as many Americans smoking as possible, a much different form of advertising than an advertisement for Paul Mall cigarettes depicting cigarettes to â€Å"Guard against throat-scratch. † When children are exposed to such stimulation of such appealing products, According to Lou Cooper, they have the influence over their parents to utilize close to â€Å"1. 88 trillion dollars†, which of course makes children a hefty target, but at what cost? Cooper 24). Advertisers use many forms of marketing to charm children. Phrases and slogans are one example. Many types  of food have a phrase associated with them. Commercials use phrases and slogans to embed their product into an audience’s memory. By the time the commercial ends the line and product are stuck in a person’s mind. By targe ting children, whole families are then targeted. Competition sparks the creation of phrases and slogans so as to imprint that brand into the minds of consumers. If one company can create a phrase that everyone will know and remember, they are one step ahead of their competition. Characters are also a way used to target children. Making characters has been the way in which many companies capture the attention of children everywhere. When a child sees commercials on television, the characters are instantly installed in their brain. Prominent figures also bring forth an ethical appeal for children; for example, in Lucky Strike advertisement, Santa Claus is shown with his bag of toys in one hand and a cigarette in the other. When the child witnesses such extreme behavior from the ones they hold dear, they want to be just like the people they admire. Therefore, children are more likely to buy a product used by their favorite celebrity or character. Toys are another way in which companies target children. Companies give toys to children sometimes relating to their product to endorse their item and entice the recipient to the merchandise. The hope some companies have is that the child will associate their brand with a reward such as a toy and want it more because of the attraction. For example, cereal companies are famous for toy advertisements. If they put toys in the boxes of cereal, children are more likely to want the box with a toy in it. Pleasing children is a main concern for all big companies. In closing, advertising to children isn’t the best idea when you want to keep the youth of our country safe, healthy, and uncorrupt so as to brighten our future as a nation. The products of some endorsements are mainly those that need to be feared. However, when a child is just as innocent as watching their favorite television show, parents and the children themselves shouldn’t need to worry about what kind of commercials pop-up that try to entice them with that happy meal and those toys. Children deserve every right to enjoy their time of being care-free and trusting. Childhood is a time for joyful bliss and innocence, not corruption.

DeTocquevilles Benefits of Democracy Compared With the...

DeTocqueville noticed three significant benefits of democracy while observing it first hand in America. Those benefits are public spirit, a notion of rights, and respect for the law. Keeping these results of democracy in mind, while reading Thoreau’s Walden a reader will wonder whether or not the author is comfortable with the notion of living in a democratic government. To answer this question, it is useful to assess DeTocqueville’s benefits of democracy and compare them with the principles found in Walden. Of the first benefit, public spirit, DeTocqueville describes two types of patriotism. The first is based on a pride of family and country and â€Å"a reverence for traditions of the past,† resulting in a strong felt personal†¦show more content†¦While Thoreau also has a strong sense of rights, he is a bit more like Rousseau in his thought, assuming that all are able to put aside their greed and their tendency to put their self interest above the self interest of others, basing much of his arguments on the presupposition that the nature of man is generally good. Operating under this assumption, Thoreau â€Å"never fastened [his] door night or day. His argument was that if all were to live as he did, without striving for anything in excess of necessity, then there would be no reason for protections against robberies. Following this logic, there would be no reason for any government of any type, save to defend against people who knew not the benefits of such living. So on the issue of rights, DeTocqueville and Thoreau arrive at a similar conclusion, that virtue and rights are necessary for any good society, they arrive there coming from very different starting points. The third benefit of democracy listed by DeTocqueville is respect of the law. In DeTocqueville’s ideal democracy every citizen would engage in the election of officials and the making of laws, all seeking to maintain the self interest of the individual. Thus, having written the law themselves, the people have a sense of ownership of the law and further desire to follow it. In Thoreau’s ideal society, many of the law written under
