A Novel Method of Encryption Using Variable Block Sizes in Different Rounds.
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 4
Abstract
we know that the strength of any cipher depends on the degree of confusion and diffusion induced in it. Since most of the transformations used for this purpose are well known to every one, it gives scope for cryptanalysis. This is mainly because of the block sizes remaining constant in all the rounds; which will introduce linearity in the cipher. This helps the crypt analyzer in breaking the cipher. Therefore, we have investigated on a new technique and found that, during encryption the block cipher sizes can be varied in different rounds depending on round key. Such that, a crypt analyzer cannot analyze the transformations used due to variable block sizes being unknown in different rounds. The cryptanalysis carried out in this regard shows that the cipher obtained through this process is a strong one and cannot be broken by any crypt analytic attack. Index Terms — Cipher Text, Decryption, Encryption, Key, Permutation, Plaintext, Substitution, Variable block size.
