Cryptography Software System using Galois Field Arithmetic
Ahmed H. Desoky, Alexey Ashikhmin · 2006
Cryptography software system (CSS) is a set of tools to simulate and analyze a number of cryptography algorithms. It is written using Microsoft C# programming language and has a user friendly GUI. Arithmetic operations for encryption and decryption are in GF(28) and the analysis provides the user with the basic statistics of data before and after the application of the selected cryptography algorithm. Along with the implementation of five cryptography algorithms (affine, Vigenere, linear-feedback-shift-register, one-time-pad, and weighted sum), CSS is built modularly and the ability to add more algorithms is a definite advantage
