Quantum pseudo-random number generation method and generation system

Abstract

The invention belongs to the technical field of encryption, and discloses a quantum pseudo-random number generation method and system, and the method comprises the steps: sharing a short quantum random number between two communication parties through quantum key distribution, taking the quantum random number as a seed, inputting the seed into a pseudo-random number generator so that two communication parties share a long random number. An algorithm is simple and easy to implement, secret key generation speed is high, the safety of a secret key is guaranteed through an Hessian Bourger measurement inaccuracy principle, the quantum unclonable theorem, the relevance and non-locality of entangled particles and other physical characteristics in quantum mechanics, and therefore the random numberhas unconditional safety and true randomness; quantum key distribution and a classic pseudo-random number generation algorithm are combined, so that the advantages of the quantum key distribution andthe classic pseudo-random number generation algorithm are combined, and the defects of the two technologies are overcome; according to the invention, the security, randomness and key generation efficiency of the shared random number are improved, and the key generation cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of encryption, and in particular relates to a quantum pseudo-random number generation method and a generation system. Background technique [0002] At present, quantum communication is a new discipline that combines quantum mechanics, information theory and cryptography. It is a new communication method that uses the quantum properties of microscopic particles as information carriers to transmit secret information. Compared with classical communication methods, quantum secure communication has huge advantages in various aspects such as security, transmission efficiency, and channel capacity, which makes quantum secure communication a new focus of scientific research and a focus of technological development in the field of communication and information. New Direction. Among the many applications of quantum communication, quantum key distribution (Quantum Key Distribution, QKD), which shares a random quantum ...
