Abstract
Between the year 2003 and 2018, a considerable new and different swarm intelligence techniques have been presented in the literature for automated cryptanalysis of classical transposition cipher. This paper compares the performance of these new and different swarm intelligence techniques. Three main comparison measures are considered to assess the performance of presented swarm intelligence techniques: efficiency, effectiveness, and success rate. It is noteworthy that among the presented swarm intelligence techniques the performance of cuckoo search technique is best with respect to all the measures.
