xx大学：信息安全专业信息安全数学基础课件
首要我想介绍一下密码学与信息安全的关系。密码学?是用来保证信息安全的一种必要的手法，能够这样说，没?有密码就没有信息安全，所以密码学是信息安全的一个核?心。那么信息安全有必要是密码学的使用，即是只要提到安?全问题，其间有必要是以密码理论为基础，不能够不必密码?而谈安全，可是只是依托密码学来保证信息安全也是不行?的，仍是需要关于安全方面的一些立法和管理方案手法等?等，所以从技术上来说，密码学是信息安全的一个核心技?术。(First of all, I would like to introduce the relationship between cryptography and information security. Cryptography is a necessary method to ensure information security. It can be said that without a password, there is no information security, so cryptography is a core of information security. Then information security must be the use of cryptography, that is, as long as security issues are mentioned, it must be based on cryptography theory, and it is not possible to talk about security without passwords, but only relying on cryptography to ensure information security is also No, there is still a need for some legislation and management schemes on security, etc., so technically, cryptography is a core technology of information security.)
