Identity authentication method based on quantum walking and related equipment

Abstract

The invention provides an identity authentication method based on quantum walking and related equipment. The method comprises the steps: carrying out the two-step quantum walking operation in a constructed quantum walking system through preparing a single photon sequence, carrying out the Z-base measurement of the single photon sequence after the two-step quantum walking, and judging whether a participant passes the identity authentication or not through a measurement result. The identity authentication method provided by the invention is higher in feasibility and practicability, easy to prepare and less in physical resource consumption, and does not need to prepare entangled quantum in the early stage, so that risk leakage caused in the authentication process is avoided, and the security of identity authentication is improved. Meanwhile, according to the identity authentication method provided by the invention, experimental verification is carried out on an IBM quantum cloud platform, and a verification result accords with theoretical derivation, so that the identity authentication method provided by the invention is more practical.

Description

technical field [0001] The invention relates to the technical field of quantum identity authentication, in particular to an identity authentication method based on quantum walking and related equipment. Background technique [0002] Identity authentication refers to the credible process of verifying the identity of the network subject to confirm the identity of the network subject. It appeared around the 1960s and was applied in the field of computer technology. After a long period of development and application, identity authentication technology can be roughly divided into three stages. The first stage mainly includes static passwords, dynamic passwords, and third-party authorized logins. Although there is a risk of identity information leakage, they have not been eliminated. The second generation of identity authentication is represented by public key infrastructure PKI (Public Key Infrastructure) technology and blockchain technology. Asymmetric encryption algorithm, has...

Problems solved by technology

The third-generation identity authentication technology was proposed in the context of the rapid development of the high-speed mobile Internet, mainly focusing on emerging fields such as biological feature recognition, big data user behavior analysis, and quantum encryption. , Discrete logarithm problems, and many encryption algorithms are no longer safe, and the current identity authentication technology is facing great challenges

However, the entangled state sequence contains the key information, and there is a risk of leakage during the distribution process. At the same time, the preparation of the entangled state requires more physical resources than the preparation of single photons.
