Abstract: |
For the cryptanalysis of ciphers, other than brute-force methods, several optimisation heuristics have been tried; these efforts are computer-intensive in nature. To demonstrate the power of simple heuristic techniques not based on any optimisation formulation, we present a simple algorithm for the known ciphertext attack of 160-bit Software Encryption Algorithm (SEAL) cipher. We attempt differential and Chi-square cryptanalysis of SEAL. The concepts developed in the paper are useful in the cryptanalysis of block and stream ciphers. |
