Recently, Beijing Zhongke Guoguang Quantum Technology Co., Ltd. (hereinafter referred to as "Guoguang Quantum"), an optical quantum chip enterprise, successfully launched the world's first random number chip that can effectively resist side-channel attacks such as power supply ripple attacks - the vacuum noise chip.
In the field of information security, random number generation technology is the key to ensuring data security. However, traditional technologies have obvious deficiencies when facing side-channel attacks such as power supply ripple attacks. Zhao Yibo, the chairman of Guoguang Quantum, said that its vacuum noise chip uses the quantum fluctuation phenomenon to generate vacuum noise. This noise has a high degree of randomness and independence and is almost unaffected by external factors, thus effectively improving the security and reliability of random number generation.
Zhao Yibo further stated that, completely different from traditional schemes based on thermal noise or partial quantum noise, the random number generation process of the vacuum noise chip is based on the quantum nature of vacuum. The characteristics of its noise source are stable and difficult to be manipulated by external factors. And even in the face of extremely complex power supply ripple attacks, due to its weak correlation between the generation mechanism and power supply factors, attackers can hardly affect the quality and randomness of random numbers through power supply fluctuations.
According to news, Guoguang Quantum's vacuum noise chip cleverly applies this cutting-edge physical principle to chip design, providing a more reliable random number source for encryption algorithms and greatly enhancing the security of data encryption. It provides security technology support for key fields with extremely high information security requirements such as finance, communications, and national defense.
According to the data, Guoguang Quantum was established in December 2021 and is a high-tech enterprise focusing on optical quantum chips. At present, the company has nearly 30 authorized scheme-level and chip-level invention patents in fields such as quantum key distribution, quantum random numbers, quantum radar, ion traps, and optical quantum communication.
The demand for chip localization is becoming more and more urgent. This year, various regions such as Beijing, Shanghai, Guangzhou, Wuxi, Suzhou, and Shenzhen have successively announced a number of support policies. At the same time, many Chinese chip enterprises are immersed in research and development and are determined to break through technical barriers in various segmented fields, aiming to establish an independent, controllable, and safe China chip industry chain and supply chain system.
In addition to Guoguang Quantum mentioned above, previously, Xianxin Technology mass-produced the world's first 28nm embedded RRAM image quality adjustment chip; the research team of The Hong Kong Polytechnic University developed the world's first 16-bit quantum bit semiconductor microprocessor chip; the nanowire width standard substance research and development team of the National Institute of Metrology of China initially constructed a high-accuracy nanowire width metrology traceability system for integrated circuits based on the traceability of silicon lattice constants; the research team of the School of Integrated Circuits, the Institute of Artificial Intelligence, and the High-precision and Innovative Center for Integrated Circuits of Peking University revealed for the first time that a passive memristor circuit is a recurrent neural network and is an emergent result of the interaction of multiple memristor devices.
