iSIMP with Integrity Validation using MD5 Hash

Abstract

Communication through Internet is common now a days. Type of communication, where one need to transfer any file became vulnerable due to penetration of unknown person in network to steal the important information, it was always challenging for researchers to send or received exact information on the network and also maintain the speed of transferring file. Preventing attackers from manipulating data and integrity validity is main objectives of this research paper. In first experiments SHA-256 were used to implements for quick and secure transfer of information, later in experiments it was found that MD5 Cryptographic hash function is more secure and faster. The main objective of this paper is to measure the performance of both algorithm and fusion of algorithm give better result and accuracy level also satisfactory as compare to other algorithms. Performance of the algorithms measured on the running time and complexity of MD5 and SHA-256. The complexity of the Algorithms MD5 and SHA-256 is that the same, i.e., θ(N), however the speed is of MD5 is better than SHA-256.
