摘要
密码技术尤其是基于数学的密码理论与技术是信息安全技术的核心。概括介绍国内外分组密码、序列密码、公钥密码、数字签名和Hash函数等密码领域的研究现状,同时对它们的发展趋势进行了分析;其次,对分组密码的主要设计理论进行了较为详细的探讨与分析;最后,介绍了AES的最终算法Rijndael。
Cipher, especially based on mathematics, is the core of information security technology. This paper first introduces summarily the status Quo of block cipher, stream cipher, public-key cipher, digital signature and Hash function etc. And it also analyzes their developmental trends. Secondly, the thesis approaches and analyzes detailedly primary theory and technology of block cipher. Finally, it discusses the Rijndael algorithm(AES' algorithm).
