Rajashekarappa, K M Sunjiv Soyjaudah, Sumitra Devi K A . Overview of Linear Cryptanalysis on S-DES and Block Ciphers using Hill Cipher Method. International Journal of Computer Applications. 63, 21 ( February 2013), 47-52. DOI=10.5120/10593-5748
In this paper presents the Linear Cryptanalysis on S-DES and Symmetric Block Ciphers Using Hill Cipher Method. As a vehicle of demonstration of this concept, choose simple yet representative block ciphers such as computationally tractable versions of S-DES, for the studies. The attack presented in this paper is applicable to block structure independently of the key scheduling. The attack needs distinct known plaintexts which are a more realistic attack model in comparison with impossible differential cryptanalysis which uses chosen plaintext pairs. Moreover, linear cryptanalysis on simplified data encryption standard performed simulations on a small variant block and present the experimental results on the theoretical model of the multidimensional linear cryptanalysis using Hill Cipher method.
