Aditi Bhateja, Shailender Kumar, Himanshu Chaudhary · 2014
With the increasing usage of internet, the need of securing the information is also getting more impor tant. The most widely used technique to make the information secure is cryptog raphy. Cryptanalysis is a method to break the unrea dable cipher text without having the key. This paper describes a method of decipheri ng encrypted messages of Vigenere cipher cryptosyst ems, Simple substitution cryptosystems and LFSR based cryptosystems by some nature inspired meta-heuristic techniques like swar m intelligence and evolutionary techniques.
