Reconfigurable Cipher Processing Framework and Implementation

Cryptographic algorithms are computing-intensive. Reconfiguration techniques can change hardware by software and implement multi-grain parallelism to adapt different applications. By studying many cryptographic algorithms, Reconfigurable Cipher Processing Framework (RCPF) is proposed using the method of induction and then the values of framework parameters for RCPF is achieved. According to the framework, a reconfigurable, pipelined architecture RCPFI-g for cipher processing is implemented on Xilinx VirteX II device. 17 cryptographic algorithms have been mapped on the RCPFI-g and simulated. The simulation results show the performance and the flexibility of the implementation. The results prove the framework RCPF and the implemented architecture RCPFI-g is efficient for cipher processing.
