Design of an Intelligent SHA-1 Based Cryptographic System: A CPSO Based Approach

並列摘要


The paper puts forward the design of an intelligent SHA-1 based crypto system. For a given 512-bit message stream the intelligence of the system lies in its power of predicting the probable-colluders. Along with the conventional SHA-1 architecture, our scheme employs a predictor control block which takes the message stream from the user, and provides the log-list of the equal length bit-streams that are most likely to produce collisions with the message stream. The predictor controller uses Canonical Particle Swarm optimization (CPSO) algorithm. Besides proposing the algorithm itself, the paper also surveys the performance of the predictor when employed with different hardware platforms.
