Abstract

Some of the desirable properties a cryptographic random number generator should have are lack of bias, bit independence, unpredictiability and nonrepeatability. In this paper, we discuss how a hardware random number generator formed from simple components can provide these properties. The components include two state machines with different structures, and free-running oscillators. The generated numbers pass the DIEHARD battery of tests.
