Özet
Transposition cipher encryption is a historical encryption method which is based on swapping letter of columns on base text according to a secret key. In this paper, we present a new swap based move operator for the particle swarm optimization algorithm. We have tested the operator on transposition cipher encryption with a text size of 125, 250, 500 and 750 letter and 5, 10, 15 key lengths. The algorithm we developed has recovered the exact original key in some tests. In most cases, particularly, the algorithm have recovered 70% of the keys and in the worst case the algorithm have recovered only sequences of the original key which can make the encrypted text barely readable for the human eye and most of the words are decrypted.
