Embodiment 1

[0090] Identity authentication pass case:

[0091] The single photon sequence obtained by the participants Alice and Bob is as follows:

[0092]

[0093]

[0094] Prepared by the third-party certification body Charlie As follows:

[0095]

[0096] At the same time, assuming first with Perform a quantum walk, and then with Do a quantum walk. The results after the two-step quantum walk are shown in Table 2.

[0097] Table 2 Execution process of certified cases

[0098]

[0099] It can be seen from Table 2 that The measurement result is the same as the initial state, and the parties Alice and Bob are authenticated.

Embodiment 2

[0101] Identity authentication failed case:

[0102] Assume that the single photon sequence obtained by the participants Alice and Bob is as follows:

[0103]

[0104]

[0105] Prepared by the third-party certification body Charlie As follows:

[0106]

[0107] At the same time, assuming first with Perform a quantum walk, and then with Do a quantum walk. The results after the two-step quantum walk are shown in Table 3.

[0108] Table 3 Execution process of cases that fail certification

[0109]

[0110] due to the single photon sequence and middle and different, causing the authentication process to fail.

[0111] The invention not only proposes an identity authentication method based on quantum walking, but also verifies the method on the IBM quantum cloud platform. Experiments Simulate Controlled Shift Operators in Quantum Walks Using Quantum CNOT Gates T , using the Pauli operator mock coin operator C , using the operator X and single ph...

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...
