Abstract
A system includes a first entropy-based random number generator (RNG) circuit configured to produce a bit stream and a key generator configured to generate encryption keys using bits from the bit stream. The system also includes an encryption engine configured to encrypt bits from the bit stream and a de-multiplexer configured to receive the bit stream from the first entropy-based RNG circuit and to provide a first set of bits from the bit stream to the key generator for generation of an encryption key and a second set of bits from the bit stream to the encryption engine for encryption to produce an encrypted output value.
