下面为大家整理一篇优秀的paper代写范文- Trusted computer technology,供大家参考学习,这篇论文讨论了可信计算机技术。可信性计算机技术的安全性,体现在人们只有经过授权与认证才能在可信性计算机平台使用,如果得不到认证,任何人都无法正常操作。可信计算平台是通过BIOS来鉴别用户,为用户的使用带来安全保障。另外,可信计算机技术的系统检查功能可以在计算平台各元素之间互相认证,从而对计算机系统进行检查与判定。从系统开启时,可信计算机技术就会从信任源开始依次检查各程序,其中包括操作系统和BIOS都将得到严格的验证。

With the continuous development of Internet technology, computer is widely used in human production and life. Although computer brings convenience to human life, its security problems also have hidden dangers. Relevant research shows that most of the computer security comes from the terminal itself, under this background, the trusted computer technology that can protect the computer security is gradually paid attention to.

Credibility computer technology is widely used by people with two special characteristics, the first is its security. This is reflected in the fact that people can only use it on trusted computer platform after being authorized and authenticated. Without authentication, no one can operate normally. Trusted computing platform is to identify users through the BIOS, for the use of users to bring security.

Another characteristic of trusted computer technology is the system checking function, which can verify each other among the elements of the computing platform, so as to check and judge the computer system. When the system is turned on, the trusted computer technology checks each program, including the operating system and BIOS, starting from the trusted source. Such checks are followed by a chain of trust that monitors the security of computer systems and reduces the risk of modification and attack.

The reason why trusted computer technology can be relied on and trusted by humans is mainly because it has five key technologies, which are indispensable parts of trusted system and play a key role. The first is the technology of the signature secret key, which relies on its randomly generated RSA secret key pair of 2048 bits to authenticate and encrypt files and data. The second is secure I/o technology, which protects the path between the user and the computer's interactive software, blocking malware while data is being transmitted. For example, computer keyboard screenshots and monitoring use the secure input and output technology of trusted system. The third is the packet shielding technology, which can have a large and independent storage area, so that even if someone intruded into the computer control system, the information in the packet area can be secured. The fourth is sealed storage technology, which can bind hardware configuration information with private information, so that private data can be obtained only under the same hardware system, ensuring the security of private data. Finally, remote authentication technology, which means that the authorizer can sense the change of the user's computer, and adopt avoidance technology to reduce the interference of the software.

Nowadays, in order to protect computer security, trusted computer technology has been widely popularized. Among them, digital rights management is a big application of trusted computer technology. For example, when a user plays or downloads music on a computer, if the user does not have music copyright, through trusted platform technology, copyright holders can use remote authentication mode to reject music play and download. What's more, trusted computer technology's sealed storage feature prevents the music from playing on other computers or players. This kind of digital rights management is often used on various music platforms or music playback pages, which can play a role in copyright protection.

The popularity of computers often exposes users' personal information on the Internet, which is not conducive to property security. Trusted computer technology can be used to maintain user identity security, which can effectively prevent user identity theft. For example, a user at the time of log on to online banking transactions, users will have to drop by the bank from the remote authentication, the authentication transaction page will receive the protection of trusted computing, both Banks and users just traded on the protected page, even if the password is private information related to user input, will not be leaked or stolen.

The digital signature technology of software in computer is also the application of trusted computer technology. Digital signature technology is powerful enough to tell whether software has been modified by third parties, as well as the security of other external software. For example, when a web page to download program is provided by the person change, the program may have holes, with a Trojan virus or spyware, the user in the process of downloading and installing, signature technology of trusted computing system will find problems in the program, and then inform the user program has been modified, so as to prevent users from the installer, avoiding damage to computer system.

Trusted computer technology is used not only in people's work, but also in their leisure time. Cheating, for example, can be prevented by trusted computer technology. During the game, some players may modify the game copy to gain advantages in order to get special rights. Then trusted computer technology's memory masking, remote authentication, and secure I/O functions would come into play. These combined functions would audit the player's server and then automatically run unmodified copies, so that the player's modified copies would be useless. In addition, trusted computer systems can also be useful for empowering game modifiers, which can be used to prevent players from cheating by verifying their server code.

Conclusion: to sum up, trusted computer technology, with its powerful functions, plays a role in maintaining the safe operation of computers and has been widely used in human life and work. In this way, the development and development of security technology enable users to use the Internet with more confidence and bring convenience to personal life. It is hoped that the computer security level of our country can continue to improve, and solve the problem of network security to the greatest extent.
