AN IMPROVED PSEUDO-RANDOM GENERATOR |
摘要 |
Methodology and concomitant circuitry to generate cryptographically strong pseudo-random bit streams utilize secure block cypher encoders. Each block cypher encoder (550) has a random key (540) and a first seed (510) as an input, and the output of each encoder is fed back to connect to its input. The first seed serves as the initial input, and each subsequent input is the immediate output of the block cypher encoder. Each bit in the cryptographically strong pseudo-random bit stream is related to a first inner product between input to the block cypher encoder and a second seed (520) and a second inner product (560) between the random key and a third seed (570). |
