Security and Network Performance Evaluation of KK' Cryptographic Technique in Mobile Adhoc Networks

Abstract

In this paper, we analyze the performance, security and attack aspects of cryptographic techniques and also investigate the performance-security tradeoff for mobile adhoc networks. We propose KK' cryptographic technique and analyze the dominant issues of security, attack and various information theory characteristics of cipher texts for DES, Substitution and proposed KK' cryptographic technique. It is found that the security and information theory characteristics of proposed KK' Cryptographic and DES algorithms is much better then substitution algorithm. The performance packet delivery fraction for KK' and substitution algorithms is much better than DES algorithm. The end-to-end delay for normal AODV protocol is very less, for substitution and KK' algorithms it is moderate and for DES algorithm it is quite high. The security aspect for KK' algorithm is almost equal to DES and network performance is almost equal to substitution algorithm. Finally, we benchmark proposed KK' cryptographic algorithms in search for the better cryptographic algorithm for security in MANET.
