The availability of ideal randomness is a common assumption used not only in cryptography, but in many other areas of computer science, and engineering in general. Unfortunately, in many situations this assumption is highly unrealistic, and cryptographic systems have to be built based on imperfect sources of randomness. Motivated by these considerations, this project will investigate the validity of this assumption and consider several important scenarios where secure cryptographic systems must be built based on various kinds of imperfect randomness.
