Abstract
A system that provides a cryptographic unit that generates secret keys that are not directly accessible to software executed by a controller. The cryptographic unit can include a restrictor device, a finite state machine, a random number generator communicatively and a memory. The memory stores values generated by the random number generator. The restrictor device and the finite state machine include hardware logic that restricts access or changes to the contents of the memory.
