一种基于真随机序列和安全散列算法可靠加密FPGA设计的方法

摘要

FPGA在定制项目和具有设计重构需求的项目开发中广泛应用,随着硬件设计集成度不断提高,在一个FPGA设计中往往集成多个厂商提供的软核设计(IPCore),IPCore知识产权保护显得尤为重要.提出一种真随机序列与密钥结合,并通过安全散列算法加密验证,实现对FPGA设计中商用IPCore知识产权保护的方法.%The FPGA is widely used in the customization project and development of the needing reconstruction project. With the continuous increase of the hardware design integration,the design of the single FPGA is often integrated with the IP-Cores provided by multiple manufacturers,so the intellectual property protection of the IPCore is particularly important. A method combining the true random sequence with secret key is proposed to protect the commercial IPCore intellectual property of the FPGA design by means of the encryption verification of the security hash algorithm.
