Abstract
In light of the problem that existing reconfigurable block cipher system has low efficiency in resource utilisation,on the basis of analysing the processing characteristics of block cipher algorithm,we propose a reconfigurable clustered block cipher processing architecture (RCCPA)which is bases on Crossbar mutual-connection,study the mutual-connection network of RCCPA,the clustered registers file and its configuration mode.The RCCPA can dynamically reconfigure each processing cluster into four 32-bit clusters,two 64-bit clusters and one 128-bit cluster through the reconfiguration mutual-connection network.Besides,it can organise the reconfigurable processing RCU into a multi-pipeline processing path,which satisfies the flexibility demand of block cipher processing and improves the utilisation rate of RCU.The performance of implementing AES/DES/IEDA using RCCPA can reach as high as 2 867.2 Mbps,1 442.6 Mbps and 1 462.4 Mbps.关键词
