摘要
针对SRAM工艺FPGA应用中的安全问题,提出了一种采用双重认证(身份认证和产权认证)的保护方法。不仅能够使得非法者无法使用FPGA,而且有效防止IP核被盗用。在FPGA外部添加安全芯片,负责完成身份认证,确认使用者的合法性;在IP核内添加保护模块,与安全芯片交互完成产权认证,确认IP核的合法性。详细介绍了双重认证方法的思想、原理和实现过程,并进行了安全性分析。
For the security problem of SRAM-based FPGA, a new protection method is purposed in this paper, which uses double authentication--user authentication and property authentication. The method can prevent unauthorized user from using the system as well as the IP core from being stolen. Legality of user is assured by the extem security device, while legality of IP core is assured through the communication between protection module in IP core and the extern security device. The idea, principle and implementation are demonstrated, and a security analysis is applied on the method.
