基于身份的十进制加密技术研究

Research of ID-Based Encryption Technology on Decimal System

主要论述了基于身份的十进制的加密技术。该加密技术以AES(AdvancedEncryptionStandard)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,提出以基于身份的动态密钥概念,同时结合混沌加密算法、随机加密算法设计基于身份的十进制加密算法。该加密技术具有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合性,也有随机加密算法的加密运算的不确定性,以及混沌加密算法的密钥一次一密性。该加密技术在预付费表计中使用表明,算法具有很好的安全性。

This paper introduces ID-based decimal system encryption algorithm principle.The principle bases on AES, chaotic and random encryption algorithm.The 4 operations of AES are redesigned to be used in decimal system encryption.The algorithm has AES strong-points which has diffusion and confusion rate for plaintexts,ciphertexts and 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 prepaid meter.Applications of the algorithm shows the algorithm is very secure.
