摘　　要：由于Logistic非线性混沌系统在一定的参数下,具有初值敏感性和拓扑复杂性等特点,因此Logistic混沌系统可以作为随机序列信号发生器。同时由于集成电路在生产、制作的过程中,即使采用完全相同的设计方法和制造工艺,也会在器件上产生不可控的微小差异,这些微小差异便成为集成电路不可克隆的基础。基于此特点,提出了一种基于可编程逻辑阵列(FPGA)的双输出查找表(LUT)结构的物理不可克隆函数(PUF)的Logistic随机混沌序列信号发生器,该混沌序列发生器具有物理的唯一性,能够有效地抵抗对于系统的复制和攻击。将该系统在Xilinx公司的FPGA开发板上进行测试和验证,结果表明,同样的电路结构和配置文件在不同的FPGA开发板上能够产生不同的随机序列,提高了混沌序列的随机性。Logistic nonlinear chaotic system has many good characters such as initial value sensitivity and topological mixing in the some parameter condition,which is used to create the random sequence signal generator.Because of the attributions of randomness and uniqueness even under the exact,the same circuit layouts and manufacturing procedures,there is still an instinct unclonable difference in each integrated circuit.Therefore,a new sequence stream generator was proposed based on Logistic chaotic system and physical unclonable function designed by double output look-up-table(LUT).The output of the Logistic sequence generator was associated with a specific physical circuit.This kind of sequence generator could resist an attack such as the replication of the keys of the system.The system was designed and tested on the Xilinx FPGA board.The results show that the same architecture of the circuit and the same config file operated on the different FPGA developing board can generate the total different random chaotic sequence stream and improve the randomness of the stream.
