High-Performance Crypto Alorgithm with Many-Core Architecture

Through analyzing some characteristics and implementation strucutres of block cipher algorithm of Feistel structure and SP network,this paper gives the mechanism of block cipher suitable for reconfigurable implementation,and proposes the architecture idea of high-performance crypto algorithm with many-core architecture.The maximal use of chip circuit capacity could be realized at the expense of proper decrease of the single-core processing capability,and the experiment shows that the many-core architecture has more obvious advantage than single-core or multi-core architecture.Finally,some problems and key points are also given,including complex programming,difficult resources allocation,and relationship of cores number and chip performance.
