Genetic algorithm based Cryptanalysis has gained considerable attention due to its fast convergence time. This article proposes a Genetic Algorithm (GA) based cryptanalysis scheme for breaking the key employed in Simplified- AES. The authors' proposed GA allows them to break the key using a Known Plaintext attack requiring a lower number of Plaintext-Ciphertext pairs compared to existing solutions. Moreover, their approach allows them to break the S-AES key using also a Ciphertext-only attack. As far as they are concerned, it is the first time that GAs are used to perform this kind of attack on S-AES. Experimental results prove that their proposed fitness function along with GA have drastically reduced the search space by a factor of 10 in case of Known plain text and 1.8 in case of Ciphertext only attack.

Abstract

Genetic algorithm based Cryptanalysis has gained considerable attention due to its fast convergence time. This article proposes a Genetic Algorithm (GA) based cryptanalysis scheme for breaking the key employed in Simplified- AES. The authors' proposed GA allows them to break the key using a Known Plaintext attack requiring a lower number of Plaintext-Ciphertext pairs compared to existing solutions. Moreover, their approach allows them to break the S-AES key using also a Ciphertext-only attack. As far as they are concerned, it is the first time that GAs are used to perform this kind of attack on S-AES. Experimental results prove that their proposed fitness function along with GA have drastically reduced the search space by a factor of 10 in case of Known plain text and 1.8 in case of Ciphertext only attack.
