On the (non)Universality of the One-Time Pad

Randomization is vital in cryptography: secret keys should be randomly generated and most cryptographic primitives (e.g., encryption) must be probabilistic. As a common abstraction, it is assumed that there is a source of truly randombits available to all the participants of the system. While convenient, this assumption is often highly unrealistic, and cryptographic systems have to be built based on imperfectsources of randomness. Remarkably, this fundamental problem has received little or no… CONTINUE READING
