Abstract
A method and system for creating random cryptographic keys in hardware is described. One or more bits are generated via one or more random bit circuits. Each random bit circuit includes a sensing device coupled to a first device and a second device to compare the first device against the second device and to generate a random bit from a random state value. The generated bits from the random bit circuits are read, and a cryptographic key may then be computed based on the generated bits.
