Performance Evaluation of Cryptographic Algorithms: MES Version I and MES Version II

In this paper we are comparing two different algorithms namely Modern Encryption Standards (MES) Version I [1] and Version II [2]. MES Version I algorithm is the amalgamation of two different encryption algorithms namely TTJSA and DJSA in randomized fashion. The method is to split the file, which is to be encrypted, and encrypting the split sections of the file in various ways using TTJSA and DJSA cipher methods, while in MES Version II algorithm there is no amalgamation of different algorithms instead it is an independent encryption algorithm. The method proposed in MES Version II is achieved by applying Modified generalized Vernam cipher method to the plain text file with feedback with different block size from left to right and after that entire content is divided into two files and then combine them by taking 2nd half first and the 1st block. Again the generalized modified Vernam Cipher method again applied from left to right with different block sizes. In this paper work, we will be analyzing and evaluating the performance criteria's of both the encryption algorithms.
