We construct a two round simplified version of DES that contains all the DES components and show that its set of encryption permutations is not a group under functional composition, it is not a pure cipher ...
This work is a study of DES-like ciphers where the bitwise exclusive-or (XOR) operation in the underlying Feistel network is replaced by an arbitrary group operation. ...
We gave careful attention to the known original design criteria for components of DES, particularly the substitution S-boxes, when we designed E-DES. ...

We named these newly designed substitution boxes (S-boxes) as substitution permutation boxes (S-p-boxes), because they serve as both substitution boxes (S-boxes) as well as permutation boxes (p-boxes). ...
This method is based on composition of the action of symmetric group on Galois field and inversion map. ...
Design for Proposed S-p-Boxes The design of the suggested S-p-box is dependent on the composition of action of symmetric group S 8 on to Galois field GF 2 8 and inversion map. ...
