A set of system resources that operate in the same security domain and that share the protection of a single, common, continuous security perimeter. TrustZone (ARM) and Software Guard Extension (SGX, Intel) are examples or hardware architectures that include features to directly support the implementation of secure enclaves.
Security used to be about systems and software. As threats evolve, hardware engineers also have to familiarize themselves with trust and security terms and acronyms.
