Identity authentication method, system, device and storage medium based on super-secret encoding

Abstract

This application relates to an identity authentication method, system, device and storage medium based on ultra-secret codes. The method includes: user A and user B respectively obtain and share a shared key Key with a length of 2n through the quantum key distribution protocol; according to the shared key Key, user A prepares a Bell state entangled particle pair sequence, and the shared key Key Every two bits in the entanglement particle correspond to a Bell state entangled particle; user A sends the particle sequence in the Bell state particle sequence to user B, and sends the particle sequence to user C; according to the ultra-dense encoding of the particle sequence and particle sequence, user C User A and user B perform mutual identity authentication. The present invention completes mutual identity verification between two users through quantum ultra-dense coding and third-party measurement; performs identity authentication based on the ultra-dense coding of the Bell entangled state, and saves quantum entanglement resources under the premise of a certain verification key length .

Description

Technical field [0001] The present application relates to the field of identification, and in particular, there is an identity authentication method, system, device, and storage medium based on hyperdeal coding. Background technique [0002] Identity authentication is a process of verifying each user identity in communication, making it a good way to prevent illegal users from pretending to communicate with legal users. The safety of classic identity authentication is generally the complexity of the mathematical algorithm. Therefore, their security will be threatened in the quantum computer age. [0003] At present, although a series of studies have been carried out around identity certification, there are still some shortcomings. First, the efficiency of identity authentication is not high, and the current authentication is mostly one-on-one model, that is, each user is independently certified. In many scenarios, most users may be certified, and the efficiency of a pair of model...

Problems solved by technology

On the other hand, the current research on quantum identity authentication generally needs to prepare quantum entangled states such as Bell state, GHZ state, and GHZ-like state to complete identity authentication. For example, the scheme proposed in the prior art uses Bell state or multi-particle The entanglement characteristics of the entangled state complete identity authentication, but the preparation of the entangled state requires more physical resources than the preparation of single photons, and it is not easy to prepare under the existing optical technology, nor can it be completely measured. These technical obstacles make The practicability of preparing entangled states to complete identity authentication is greatly reduced
