Hill climb cipher
WebHillClimbing and Simulated Annealing algorithms can be used to crack Playfair ciphers as well as all other 5*5 grid based ciphers, and also simple substitution ciphers and Vigenere ciphers.

WebThere are several algorithms available which can attack a Playfair cipher. Hill climbing might be one option. Basically it starts with a random key (assuming it's the best one) and decrypts the cipher. The resulting clear text is scored using a fitness function.

The Keyphrase cipher (see an example on the ACA's site) is a simple substitution cipher where the ciphertext alphabet may contain a letter more than once. In David Kahn's "The Codebreakers" he gives the following example on page 787: Web41 Tower Climbing jobs available in Charlotte, NC on Indeed.com.

Webnecessary in order to ensure that we completely understand this complex cipher system, and moreover we will also use this simulator for the remainder of the project. Secondly, we propose to study the hill climb attack on Purple discussed in [2]. This attack uses an ad hoc approach and we believe that a more systematic hill climb attack is possible.
