Abstract
Processor system with a general purpose processor and a cryptographic processor dedicated to performing cryptographic operations and enforcing the security of critical security parameters. The cryptographic processor prevents exposure of critical security parameters outside the cryptographic processor itself, and instead implements a limited scripting engine, which can be used by the general purpose processor to execute operations that require the critical security parameters.
