True random binary sequence generator for secure communications

The true random binary sequence generator provides a secure, non-reproducible source of true random binary sequences for applications with strong security requirements, such as for generating encryption keys and for secure communications. In this paper we present a realization of true random binary sequence generator. Thermal noise found in chaotic physical system is used as a source of true randomness. NIST tests for verification of randomness are applied. Some experimental results are presented.
