(1) Issue the city master transmission card, and use the master transmission master card to issue the master transmission card. The main control transmission mother card stores the main control key in binary cipher text; the encryption key stores the main control key. Modern cryptanalysis technology includes differential cryptanalysis technology, linear cryptanalysis technology and key-related cryptanalysis. It improves the deciphering speed, but the deciphering speed is still very slow. (1) Automatically track the screen changes of the target machine, and can fully simulate keyboard and mouse input, that is, while synchronizing the screen changes of the controlled terminal, all keyboard and mouse operations on the monitoring terminal will be reflected on the screen of the controlled terminal (for local area network ) . ( Such as access control lists ) allows the user to user name and ( or ) the identity of the user group requirements and control of the shared object; prevent non- authorized users to read sensitive information, and control access proliferation. The autonomous access control mechanism only allows authorized users to specify access to objects based on the users specified by the user . In this way, sensitive information is not tampered with during the transmission of digital signatures, and other people who have not been authenticated and authorized cannot see or read the original data, which plays a role in keeping sensitive data confidential in the transmission of digital signatures. (3) to talk about your understanding of the encryption and decryption ( including the overall impression of the learning experience, the level of interest, understand the algorithm processes the application and the degree of encryption and decryption software ) . USERnalTle By modifying the key value of Start Page , the purpose of modifying the browser's IE default link homepage is achieved . The following solutions can be taken: (4) Non-repudiation, the sender’s digital certificate is only owned by the sender, so after the sender uses his digital certificate to digitally sign the email before transmission, the sender cannot deny sending the email.

(3) As a security checkpoint, the firewall can effectively filter, screen and shield harmful information and services. When a function call occurs in the program, the computer does the following: first push the parameters onto the stack and save the instruction register Research on the principles and coping methods of distributed denial of service has been ongoing, and finding an effective and feasible solution is not a matter of overnight. But at least you can maintain your own network and host well. Firstly, let your host not be used by others to attack others; secondly, when you are under attack, try to save evidence so that you can trace it afterwards. The network and system logs are necessary. No matter where the defense of distributed denial of service attacks develops, this will be a social project that requires the attention and cooperation of colleagues in the IT industry.
