2017 International Journal of Computer Applications  
Differential Cryptanalysis is a powerful technique in cryptanalysis, applied to symmetric-key block ciphers. It is a chosen plain-text attack which means the cryptanalyst has some sets of the plain-text and the corresponding cipher-text pairs of his choice. These pairs of the plain-text are related by a constant difference. Basically it is the study of how differences in input information can affect the resultant difference at the output. In this paper, differential cryptanalysis is applied on

The survey is based on the analysis of a simple, yet realistically structured, basic Substitution-Permutation Network cipher. Along with this, the paper also presents our contribution in this paper as well as our future research work.
