Secure and trustworthy execution in heterogeneous SoCs is a major priority in the modern computing system. Security of SoCs mainly addresses two broad layers of trust issues: 1. Protection against hardware security threats(Side-channel, IP Privacy, Cloning, Fault Injection, and Denial of Service); and 2. Protection against malicious software attacks running on SoC processors. To resist malicious software-level attackers from gaining unauthorized access and compromising security, we propose a

TrustToken builds a security block to provide a root of trust-based IP security: secure key generation and truly random source. TrustToken only allows trusted communication between the non-trusted third-party IP and the rest of the SoC world by providing essential security features, i.e., secure, isolated execution, and trusted user interaction. The proposed design achieves this by interconnecting the third-party IP interface to TrustToken Controller and checking IP authorization(Token) signals at run-time. TrustToken architecture shows a very low overhead resource utilization LUT (618, 1.16 %), FF (44, 0.04 %), and BUFG (2 , 6.25%) in implementation. The experiment results show that TrustToken can provide a secure, low-cost, and trusted solution for non-trusted SoC IPs.
