1. A method in a processor comprising: generating a root key within a security boundary of the processor from a source of static and entropic bits of the processor, wherein the source of the static and entropic bits is included on a die; deriving one or more keys from the root key within the security boundary of the processor and on the die; and performing cryptographic primitive operations based on the root key within the security boundary of the processor and on the die, wherein the processor comprises at least one general-purpose core.
