Beijing Zhongke Guoguang Quantum Launches World's First Vacuum Noise Chip to Resist Side-Channel Attacks

TapTechNews September 22nd news, according to the Beijing Yizhuang public account, recently, Beijing Zhongke Guoguang Quantum Technology Co., Ltd. (hereinafter referred to as Guoguang Quantum) successfully launched the world's first random number chip that can effectively resist side-channel attacks such as power supply ripple attacks - vacuum noise chip.

It is introduced that in the field of information security, random number generation technology is the key to ensuring data security, but traditional technologies have obvious deficiencies when facing side-channel attacks such as power supply ripple attacks.

Guoguang Quantum's vacuum noise chip utilizes the vacuum noise generated by the quantum fluctuation phenomenon, which has a high degree of randomness and independence, and is almost unaffected by external factors, thereby effectively improving the security and reliability of random number generation.

Specifically, 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 the weak correlation of its generation mechanism with power supply factors, attackers can hardly affect the quality and randomness of random numbers through the fluctuation of power supply.

TapTechNews learned from publicly available information that Beijing Zhongke Guoguang Quantum Technology Co., Ltd. was established in 2021 and is committed to the development and application of quantum chips. The company currently has nearly 30 authorized scheme-level and chip-level invention patents in the fields of quantum key distribution, quantum random numbers, quantum radar, ion traps, and optical quantum communication.
