Jun Yang, Ding Jun, Li Na, Guo Yixiong · 2010
This paper uses the similarity between SHA-224 and SHA-256 algorithms to design the SHA-224/256 IP core oriented Digital Signature. The IP core uses parallel structure and pipeline technology to simplify the hardware design and improve the speed by 26%. Finally this IP core is implemented on the Altera's FPGA EP2C20F484C6 chip. And its simulation result can run rightly under the 100MHz frequency. This IP core can be widely used in the data integrity and consistency verification, pseudo random number generation and other areas of cryptography.
