摘要
介绍了在信息安全中起到重要作用的加密技术及其算法,比较了对称密码加密系统与公钥密码加密系统各自的优缺点,并探讨了改进的几种方法及其应用。密钥分配是保证安全性的关键。应从密钥的简单性、成本的低廉性,管理的简易性,算法的复杂性、保密的安全性及计算的快速性等方面综合考虑加密系统技术的改进。
This paper mainly discusses the realizable way of the recoding technology, analyzing the advantages and disadvantages of the secret key cryptography system, comparing the features of private key cryptography with those of public key cryptography encoding technology to show their different suitable limits, and presenting some improved encoding technology algorithms as well as their application.
