Research of Encryption Algorithm Based on Dynamic Update Permutation Table
On the basis of classic monoalphabetic permutation eryptosystem,an encryption algorithm based on Dynamic Update Permutation Table is proposed and implemented in this paper,which combines the methods of byteswapping and dynamic cyclic shift.The encryption algorithm is easy to be understood and implemented.It overcomes the weaknesses of previous permutation cryptosystem.The speed of encryption and decryption is very fast,and the security has been greatly improved.It can also resist many cryptanalysis effectively such as statistical analysis,and meets encryption needs at the different levels.In addition,the key management,efficiency of data processing and the security of algorithm are also studied and analyzed in this paper.
