基于SHA-1算法的FPGA加密设计

Encryption Design based on SHA-1 Algorithm of FPGA

为了解决基于SRAM工艺的FPGA的保密性问题,通过利用SHA-1加密算法,在身份验证的过程中将产生随机数的种子随机化和验证时间间隔随机化的双重随机化方法,实现了高可靠性能FPGA系统加密。该设计具有较高的抗追踪性,可有效地防止对芯片的非法拷贝。

encryption randomizing copying of In order to solve the issues of confidentiality with FPGA based on SP, AM technology, it achieved high reliability FPGA system by SHA 1 encryption algorithm and double randomization method which is generating of the random number of seeds randomly and of the intervals of certification. The design has a high resistance to the track of sexual, which can effectively prevent the illegal chip.
