We present permutation code encryption which is based on path encryption. Now permutation code encryption is a patent of Chinese invention. In Permutation Code Encryption, we use a pseudo-random sequence of the keys to control the paths. The simulation result shows that for n-bit block the encryption strength is novel higher than 2^n and the algorithm can finish the encryption of one block in 7.5 ns, which is unrelated with the block length.展开更多
