Abstract

We use simulated annealing to provide an automated method for the cryptanalysis of mono-alphabetic substitution ciphers. We prove the convergence of the algorithm and study its performance for a specific cooling schedule. We discuss the merits of this approach and show that it provides a simple, fast and elegant solution to the cryptanalysis problem which is also promising for more complex types of block ciphers.
