<p>Methodology and concomitant circuitry to generate cryptographically strong pseudo-random bit streams utilize secure block cypher encoders. Typically, each block cypher encoder (150) has a first seed (x0) and a random key (k) as an input. In the most basic realization of the methodology and circuitry, the ouput of each encoder is fed back (151) to connect to its input. The first seed serves as the initial input, and each subsequent input is the immediate output. Each bit in the cryptographically strong pseudo-random bit stream is related (160) to an inner product between each input to the encoder and a second seed (h).</p> |
