The author surveys problems in generating and using pseudorandom numbers. He deals with some general principles for constructing pseudorandom bit generators and its underlying group-theoretic or number-theoretic structure. Some pseudorandom bit generators are described explicitly.
The author describes the subject of computational information theory and its connection to cryptography. The basic object in this theory is the concept of a secure pseudorandom bit generator. Essential properties of pseudorandom generators, especially of secure pseudorandom bit generators, are described. Results on the statistical performance of various known pseudorandom number generators are discussed with respect to suitability for cryptographic uses. It is shown that a special pseudorandom bit generator, called the RSA generator, produces secure pseudorandom bits if the problem of factoring certain integers is computationally difficult.
