基于自治布尔网络的高速物理随机数发生器研究
High-speed physical random number generator based on autonomous Boolean networks
摘要
Abstract
Using deterministic mathematical algorithms can produce fast pseudo-random numbers. However, their predictability makes them difficult to guarantee the security of communication. Unpredictable random numbers can be extracted from chaotic circuits, called physical random number generators (physical-RNGs). But the bandwidths of the conventional chaotic circuits limit their generation bit rates. A novel physical-RNG by utilizing the autonomous Boolean network which can produce wideband chaotic signals was designed. The results show that the physical-RNG can produce physical random bits stream at a speed up to 10 Gbit/s. The physical random numbers generated by the physical-RNG own good random characteristics. The physical-RNG can be conveniently applied in data encryption and secure communications.关键词
