Performance Comparison of Cryptanalysis Techniques over DES
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 5
Abstract
The primary requirement of a good encryption technique is that it is either impossible or difficult to deduce the plaintext out of a ciphertext without the knowledge of key. Cryptanalysis is the technique that violates this requirement. It focuses on either determining the plaintext out of a ciphertext or guessing the key without trying all the possible combinations of key. Since the development of DES (Data Encryption Standard) in 1977 many cryptanalysis methods have been developed and improved to test security provided by it. Two of the widely used techniques are Linear and Differential cryptanalysis. This paper is aimed at comparing the efficiency of these cryptanalysis methods over Brute Force approach based on experimental results carried out on S-DES. The performances of these methods are compared based on time required for guessing the actual key.
