D-crypt is an symmetrical block cipher operating on 256bit blocks with an key of the same length. The cipher takes 3 inputs: the data to encrypt, the symmetric key and a tweak consisting in a array of 16 integers representing each one of eleven possible keyaddition algorithms. Features a similar structure as AES (uses simpler versions of ShiftRows, MixColumns) and uses AES SBOX. It is an SP network. The Key Schedule is a different from AES's, however the Expansion is partially inspired in AES. The 256-bit key is turned into a 576-byte expanded key which is used in every key addition round. ...
