Poly Substitution Method for Encryption and Decryption
Journal Title: International Journal on Computer Science and Engineering - Year 2010, Vol 2, Issue 5
Abstract
In this study we explore the features of Genetic Algorithm with poly substitution methods to generate ASCII values of the given text and then applying conversion, transposition with the features of Cryptography. In PS ciphers the plaintext letters are enciphered differently depending upon their placement in the text. As the name polyalphabetic suggests this is achieved by using several two, three keys and random keys ombinations instead of just one, as is the case in most of the simpler crypto systems. Using two keys, we take 2 keys e1,e2 and let the SCII values of e1 be 1 and e2 be 2 and take the text, add SCII alues of e1 to first character and ASCII values of e2 to second character. Alternatively add the value of e1 and e2 to consecutive characters.
