资料介绍

鉴于激光器系统的实验成本较高,提出一种用模拟电路代替单环掺铒光纤激光器系统产生混沌信号的方法,得到真随机序列。这组随机序列能够通过NIST软件包的16项测试,具有良好的随机性。将此真随机序列用于图像加密,实验证明,此方案能够抵抗各种攻击,具有较高的安全性。

In view of high experimental cost of laser system, this paper is intended to make substitution experiment of artificial circuit for erbium-doped fiber ring laser. After post-processing, a random number sequence is realized and the randomness is verified by the NIST special publication tests. This physical true random sequence can be applied to digital image encryption. Experiment results show that the proposed scheme has a large key space together with excellent statistical properties. It has good feasibility and safety which can resist all kinds of attacks.
