Designing and Building a NIST SP 800-90 Compliant Hardware Entropy SourceIn this project, we designed and implemented a random number generator (entropy source) based on a NIST recommendation (NIST SP800-90). We also integrated into our generator the entropy estimators proposed by NIST and ran performanmce tests both in terms of speed and amount of entropy. The amount of entropy we generate is acceptable even when we use camera images that do not change quickly (but still has some noise). On the other hand, entropy estimation is slow and it is currently a bottleneck in our implementation. In the future, we plan to optimize some of the entropy estimations to increase speed, and we also want to use other types of random noise sources.
