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

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.
