Conditioner and Health Monitor for Use in Conjunction with a Random Bit Generator
Richard Newell

| Two circuit blocks often needed in conjunction with a physical random bit source are a Conditioner and a Health Monitor. The Health monitor is used to make sure that the physical source is generating sufficient entropy and hasn't failed. The Conditioner concentrates the available entropy and ensures that its output is statistically indistinguishable from true random numbers. Efficient examples of both circuits are proposed that are suitable for FPGA implementations. |
