基于十进制的加密技术研究

Research of Encryption Technology Based on Decimal System

本文主要论述了基于十进制的加密技术.以美国最新对称加密标准AES(A dvanced Encryption S tandard)为基础,对AES的4种加密运算进行重新设计,以适应十进制数的加密,同时结合混沌加密算法、随机加密算法设计基于十进制的加密算法.该算法具有AES加密算法的特点,对明文和密文均具有很好的扩散性和混淆性,也有随机加密算法的加密运算的不确定性,也有混沌加密算法的密钥一次一密性.该算法适用于不可靠通信信道上的十进制数加密通信,能在预付费表计等实际系统中得到广泛的应用,实践证明该算法有很高的安全性.

This paper introduced decimal system encryption algorithm principle. The principle based on AES, chaotic and random encryption algorithm. The 4 operations of AES was redesigned to be used in decimal system encryption. The algorithm had AES strong-points which has diffusion and confusion rate of plaintexts and ciphertexts for key, random encryption algorithm which is operation＇s indeterminacy and chaotic encryption algorithm which is one key once. It can be used in decimal system encryption in trustless channel, especially in prepaid meter. Applications of the algorithm showed the algorithm is very secure.
