Hong Zhong · Jisuanji gongcheng · 2012
This paper proposes a decimal system encryption algorithm based on Feistel network.Aiming at the characteristics of decimal system operations,four operations are defined in encryption algorithm,two operations are defined in key expansion algorithm and decryption algorithm,and the new decimal system substitution table is designed.The new encryption algorithm is applied to the short-block encryption simulation system,simulation results show that the proposed algorithm has excellent cryptographic properties,all diffusion rate targets reach desired impact,and the diffusion rate of key to ciphertext after 6-round encryption reaches full diffusion.The encryption algorithm can be applied to all areas of decimal system encryption.
