Design and Analysis of Interconnection Network of Reconfigurable Cryptographic Processor

The reconfigurable cryptographic processor is an integrated circuit that is used for data encryption or decryption. The logic structure and function of this processor is reconfigurable, so it can implement many different cipher algorithms flexibly and quickly. The interconnection network of the reconfigurable cryptographic processor is the data transmission path, so it has very important influence on the flexibility, performance and scale of the processor. In this paper, several conceptions such as connectivity, network width, network scale have been proposed, some design principles of the interconnection network have been given, three typical interconnection networks named all interconnected, single bus, multiple bus have been introduced and their features have been analyzed.
