Why Hardware Root of Trust Needs Anti-Tampering Design
The hardware root of trust (HRoT) provides the trust base (root key), hardware identifier (UID), hardware unique key (HUK), and entropy required for the secure operation of the entire chip and therefore is often the focus of hacker attacks. If the design can’t effectively resist attacks, hackers can easily obtain the secrets of the entire chip. Attackers can use the secrets to crack identity authentication and data encryption and steal product design know-how, causing application security problems.
