一种基于IDEA的十进制短分组加密算法
Decimal system short-block encryption algorithm based on IDEA
摘要
Abstract
The international data encryption algorithm is a well-known cryptosystem that is widely used in various fields, such as PGR.In this paper, a novel decimal system short-block encryption algorithm based on IDEA algorithm is proposed. Aiming at the characteristics of decimal system operations, 3 new operations are defined,and the theoretical proof of the reversibility of the decimal system encryption algorithm is given.The new encryption algorithm is applied to the short-block encryption simulation system.The simulation results show that the proposed algorithm has excellent cryptographic properties, I.e., all diffusion rate targets reach desired impact,and the diffusion rate of plaintext to ciphertext after the first round encryption reachs full diffusion.The encryption algorithm can be applied to all fields of decimal system encryption.关键词
