Abstract

A processor of an aspect includes root key generation logic to generate a root key. The root key generation logic includes a source of static and entropic bits. The processor also includes key derivation logic coupled with the root key generation logic. The key derivation logic is to derive one or more keys from the root key. The processor also includes cryptographic primitive logic coupled with the root key generation logic. The cryptographic primitive logic is to perform cryptographic operations. The processor also includes a security boundary containing the root key generation logic, the key derivation logic, and the cryptographic primitive logic. Other processors, methods, and systems are also disclosed.
