Method and apparatus for a trust processor

A non-transitory machine-readable medium that provides instructions, which when executed by a machine, cause said machine to perform operations comprising:

• receiving a primitive instruction into a cryptographic processor from an application processor through a direct memory access logic, wherein the cryptographic processor, the application processor, and the direct memory access logic are within a system-on-a chip;
• retrieving at least one microcode instruction from a memory within the cryptographic processor based on the primitive instruction;
• determining whether one of the at least one microcode instruction is related to a sensitive operation;
• determining whether the cryptographic processor is in a trusted state based on whether the cryptographic processor is properly initialized;
• executing the at least one microcode instruction when the at least one microcode instruction is a sensitive operation and the cryptographic processor is in a trusted state;
• and
• precluding execution of the at least one microcode instruction when the at least one microcodeinstruction is a sensitive operation and the cryptographic processor is in an untrusted state.
