Abstract
Some implementations disclosed herein provide techniques and arrangements for provisioning keys to integrated circuits/processor. In one embodiments, a key provisioner/tester apparatus may include a memory device to receive a unique hardware key generated by a first logic of a processor. The key provisioner/tester apparatus may further include a cipher device to permanently store an encrypted first key in nonvolatile memory of the processor, detect whether the stored encrypted first key is valid, and to isolate at least one of the first logic and the nonvolatile memory of the processor from all sources that are exterior to the processor in response to detecting that the stored encrypted first key is valid.
