真随机数发生器（ True Random Number Generator， TRNG）是保密通信系统以及信息安全芯片中的重要单元之一，用来产生系统所需要的真随机数序列，从而实现通信加密或者身份认证。对传统的基于模拟随机源的真随机数发生器结构进行了改进，在随机源后加入数字处理单元，包含曼彻斯特编码器、线性反馈移位寄存器（ Linear Feedback Shift Reg?ister， LFSR）和AES运算单元。模拟随机源产生的真随机数序列在经过数字电路的后处理后，再送入系统中进行使用。数模混合仿真结果显示，该结构可有效提高真随机数的随机性指标，提高系统和芯片的加密性能，保障通信及数据安全。

True random number generator ( TRNG) is one important element in secure communication system and information security chip,which is used to generate true random number sequences required by the system to realize the communication encryption or authentication.In this paper,the traditional true random number generator based on the structure of analog random source was im?proved.The digital processing unit is added after in the random source which consists of Manchester encoder,linear feedback shift regis?ter (LFSR) and the AES operation unit.The true random number sequence generated by the analog random source is sent to use in sys?tem after the digital circuit processing.Digital and analog co?simulation results show that the Structure of TRNG effectively improves the random index of the true random number sequence,so as to improve the encryption performance of the system or the chip and guarantee communication security and data security.
