Efficient double-factor cross-domain authentication method based on block chain technology

Abstract

The invention relates to an efficient double-factor cross-domain authentication method based on a block chain technology, which is characterized by comprising the following steps: 1, designing an overall architecture of a system; 2, realizing a system workflow; step 21, carrying out a user registration process; 22, performing local authentication on the user; and step 23, performing cross-domain authentication on the user remotely. According to the equipment number and password double-factor cross-domain authentication scheme provided by the invention, the cross-domain authentication efficiency of the user is improved, and the safety of cross-domain authentication of the user is ensured.

Description

technical field [0001] The invention belongs to the field of PKI authentication cross-domain authentication, in particular to an efficient two-factor cross-domain authentication method based on block chain technology. Background technique [0002] In the electric vehicle time-sharing rental sharing platform, users are required to use vehicles across platforms, that is, users of A electric vehicle time-sharing rental company can use vehicles operated by all other companies B, C, D, etc. in the alliance, which can satisfy users to the greatest extent. For daily travel needs, users no longer need to use the apps of multiple electric car rental companies and pay multiple deposits, and companies such as B, C, and D can obtain the car rental business of users of Company A without spending high customer acquisition costs. [0003] However, in a distributed environment, for the convenience of managing users, each company and department sets up a corresponding resource access control...

Problems solved by technology

[0011] However, the schemes of Zhou, Zhang and others are not completely applicable to the system designed in this paper. There are three main reasons for this. First, there are many users involved in the electric vehicle time-sharing rental sharing platform, and the equipment used by users is uneven. There is no uniform biometric collection equipment; second, biometrics are different from other characteristics and cannot be changed by the individual user. When it comes to biometric collection, users will worry about biometric leakage, which is not conducive to the promotion of the system. ; The third is that fuzzy extraction technology and recovery algorithm need to be frequently used in the authentication process, and the efficiency is low in the case of a large number of users with high concurrent requests
