Abstract
A system-on-chip (SoC) includes multiple hardware modules that are implemented on a substrate. The hardware modules include a plurality of hardware and software security features and the SoC provides one or more external interfaces for accessing the security features. A validation module, implemented in the boot code of the SoC for example, manages security certificates to control access to the plurality of security features. Each security certificate includes one or more unique identifiers corresponding to one or more hardware modules in the SoC and access control settings for one or more security features of the one or more hardware modules. The security certificate additionally includes a certificate signature signed by a secure key.
