The Team of Lanzhou University Information College successfully developed high throughput pseudo -random random generators

The random sequence in engineering technology is generally generated by the pseudo -random number generator, which is widely used in information security, signal processing, system simulation and quantum simulation. The development of pseudo -random number generators is a basic technology in many application fields such as national defense security, instrument and equipment manufacturing, privacy protection, and encrypted communication. With the rapid improvement of network bandwidth, high -quality and high throughput pseudo -random generators are essential to enhance the development of network security and communication equipment. At present, the international high -level pseudo -random pulse serial generator is the KEYSIGHT 81134A produced by the Aglen company in the United States, with an throughput of 3.35 GB/s and a price of up to 140,000 yuan/set. In public reports, no throughput can break through 10Gbps related products and research projects.

Recently, the 2019 undergraduate students at the School of Electronic Information Science and Technology, the School of Information Science and Engineering, Lanzhou University, have made a breakthrough in this direction under the guidance of Li Shouliang, Yang Zhen and Ren Fengyuan. The pseudo -random number generator with a throughput of up to 10.4Gbps. In response to the shortage of most of the parameters of the chaos system and the shortcomings of the existence cycle window, the research proposed a cross -feedback non -linear coupling ultra -chaos system. More complex dynamic behavior. Pseudo -random number generator based on discrete and chaos can generate random random sequences with low calculation complexity. After the industrialization of related technology, it is expected to achieve the world's leading position in the field of pseudo -random generator development.

The study adopted FPGA to implement a pseudo -random number generator based on discrete and chaos, and conducted basic functional verification and performance evaluation. The generated random sequence passes the evaluation of random number test software released by international authoritative institutions such as NIST, TESTU01 and Diehard, and has the ability to provide the basic services for key generation for "one secret" security communication in ultra -high -speed networks. At the same time, compared with the traditional pseudo -random number generator products, the products developed based on the discrete super chaos system have the advantages of low cost, small power consumption, easy miniaturization, and IP nuclearization. In the center of smart network cards such as the center, it can also be applied to mobile devices and embedded devices, thereby enhancing the security of infrastructure such as the industrial Internet network.
