Cryptology is the science and study of systems for secret communication. In consists of two complementary fields of study: cryptography and cryptanalysis. This study presents a cryptanalysis method based on Genetic Algorithm and Tabu Search to break a Mono-Alphabetic Substitution Cipher in Adhoc networks. We have also compared and analyzed the performance of these algorithms in automated attacks on Mono-alphabetic Substitution Cipher. The use of Tabu search is largely an unexplored area in the field of Cryptanalysis. A generalized version of these algorithms can be used for attacking other ciphers as well.}, journal = {Journal of Computer Science}, publisher = {Science Publications} }
