A Novel Design of Flexible Crypto Coprocessor and Its Application
Accelerating security protocols has been a great challenge in general-purpose processor due to the complexity of crypto algorithms.Most crypto algorithms are employed at the function level among different security protocols.We propose a novel flexible crypto coprocessor architecture that relies on Reconfigurable Cryptographic Blocks (RCBs) to achieve a balance between high performance and flexibility and implement the architecture for security application on FPGA.The pipelining technique is adopted to realize parallel data and to reduce the commication costs.We consider several crypto algorithms as examples to illustrate the design of the RCB in the FC Coprocessor.Finally,we create a prototype of the FC coprocessor on a Xilinx XC5VLX330 FPGA chip.The experiment results show that the coprocessor,running at 216 MHz,outperforms the software-based file encryption running on an Intel Core i3 530 CPU at 2.93 GHz by a factor of 29× for typical encrypt application.
