摘要： A random number generator uses a looped circuit that produces pulses dependent on manufacturing variations and noise, and fed into a counting circuit. In certain embodiments, the technology can be merged with a Physical Unclonable Function (PUF) such that a single circuit provides both 1) bits that are unique to each chip that remain fairly similar each time they are queried on the same chip; as well as 2) bits that are random, i.e., different each time the randomness is queried, even on the same device.

摘要： A system and methods are disclosed that limiting the number of challenge/response pairs available to an adversary. In accordance with the various aspects of the present invention, gate the access to an authentication module with a gatekeeper. The system can create a challenge/response protocol whereby the amount of challenge/response information leaked is controlled by the server. The device cannot leak challenge/response pairs when the device is in the possession of or being queried by an adversary or false device.
