Optimization of encryption technique using evolutionary algorithm for protecting multimedia contents in P2P system

With the growth of usage of file sharing applications over internet, Peer-to-Peer (P2P) networking system has recently drawn attentions of the researchers for various causes right from QoS issues to Security flaws. Due to absence of any centralized administrative management in P2P system, the network becomes highly vulnerable for various types of attacks. Therefore, the current paper discusses about a novel technique that uses recurrence relation to generate number of encryption version of the multimedia content, which is further more strengthened using optimization technique. Evolutionary Algorithm is considered for optimizing the encryption process. The accomplished results are finally evaluated with respect to correlation coefficient among the adjacent pixels, key analysis, and highest entropy of frames.
