Authentication method, authentication device and system applied to intelligent terminal

Abstract

The invention provides an authentication method, an authentication device and a system applied to an intelligent terminal. The method includes the steps that an applied account number is bound with a public key of the authentication device which is carried along with a user; the intelligent terminal receives the verification request of at least one application, and the verification request requests that the signing message sent back by the authentication device is used for conducting verification; based on the verification request, the near-field communication function is used for sending the verification request message to the authentication device near the intelligent terminal by a certain distance; the authentication device uses a private key preset in the authentication device and a designated cryptographic algorithm to conduct signing on the verification message, and the signed verification request message is sent back to the application; the public key, bound in advance, of the authentication device and the designated cryptographic algorithm are used for verifying the verification request signing message which is sent back, and a verification result is obtained. By means of the authentication method, the authentication device and the system applied to the intelligent terminal, the problems of inadequate safety, complex operation and high cost in the application verification process in the prior art can be solved.

Description

technical field [0001] The invention relates to the communication field, in particular to a user identity verification method, identity verification device and system for smart terminal applications. Background technique [0002] With the development of communication and mobile Internet technologies, various smart terminals have more and more functions and become more and more powerful. Smart terminal applications, mainly represented by mobile e-commerce, mobile payment, mobile banking, and online games, provide users with more convenient and efficient services. Various applications developed for various mobile phones are also emerging in an endless stream. When users use applications on mobile phones, they often need to perform identity verification operations. At present, there are three mainstream smart terminal identity verification methods: account password method, SMS verification code method and USB-shield digital certificate method. For example, when the mobile pho...

Problems solved by technology

However, the U-Shield is independent of each application platform, and cannot be used in common with each other, and has a single function, so it can only be used as an identity verification for the financial function of its own platform.

Users generally need identity verification of multiple application platforms, so they need to carry multiple U-shields, which is expensive and inconvenient to carry, so it is not very popular with users
