Paper Title : Modern Encryption Standard version IV: (MES-IV)
Author Name : Asoke Nath, Payel Pal
Abstract : In the present paper the authors have introduced a new cryptographic method named as Modern Encryption System Standard version IV which is basically a symmetric key cryptographic method. Here the authors have used three different type of cryptographic methods .Those method are columnar transposition method, bit level generalized vernam cipher method with feedback and bit wise XOR operation. This system is the extension of MES-III and partly Bit level Encryption Standard (BLES) –II and III. BLES-I, II, III and MES-I, II, III developed by Nath et al where MES-I, II, III mostly based on mainly byte level encryption method. BLES-I, II and III are based on mostly bit level encryption methods. In the present MES-IV method authors have tried to combine different bit level encryption to make the entire encryption system more secured. The introduction of feedback in bit level generalized vernam cipher method prevents attacks such as differential attack or plain text attack. The random key generator has been used to construct the keypad for vernam cipher method. The present encryption method is free from common attacks and it is almost impossible to break the present method without knowing the exact key and the methods. This encryption method will be used to encrypt password, short messages, financial data etc.
Keywords : Plain text, Cipher text, Randomization, Columnar Transposition, Feedback .
