Abstract
Techniques for encrypting data using a key generated by a physical unclonable function (PUF) or a virtual PUF key are described. An apparatus according to the present disclosure may include decoder circuitry to decode an instance of a single instruction having a field for an opcode to indicate that execution circuitry is to encrypt at least encrypt secret information from an input data structure with either a physical unclonable function (PUF) generated encryption key or a virtual PUF key, bind the wrapped secret information to an identified target, update the input data structure, generate a MAC over the updated data structure, store the MAC in the input data structure to generate a wrapped output data structure, store the wrapped output data structure having the encrypted secret information and an indication of the target.
