Automated cryptanalysis of substitution permutation network cipher
The encryption algorithm uses a 10-round Feistel structure and is based on the concept of a substitution-permutation network (SPN).
My ANGELITA 128-bit SPN Cipher, now in Python
Implementation of an SP Network using a new modified Playfair Cipher for substitution and the chaotic Logistic-Tent Map for permutation, in Python. This new algorithm has been named Playfair Logistic-Tent Network (PLT-Net).
