Researchers including academician Pan Jianwei from the University of Science and Technology of China have successfully developed a set of quantum random number generators based on device-independent entropy sources, and applied them to zero-knowledge proof fields as random number beacons for quantum cryptography for identity authentication. This eliminates the security risks brought by the difficulty of implementing true random numbers in non-interactive zero-knowledge proofs, and improves the security of non-interactive zero-knowledge proofs. Non-interactive zero-knowledge proofs are widely used in digital signatures, blockchain, and identity authentication, and because true random number generators are difficult to implement, deterministic pseudorandom number algorithms are usually used instead. It is understood that this research work has combined three different fields of quantum non-locality, quantum security algorithms, and zero-knowledge proofs for the first time, greatly improving the security of zero-knowledge proofs. The public-oriented random number service built has important application potential in cryptography, lottery industry, and social welfare.
