Problems solved by technology

On the server side that provides data, because the external interface basically adopts the HTTP (Hypertext Transfer Protocol, Hypertext Transfer Protocol) protocol, the use of encryption and signature is less, and there is a great hidden danger
In the financial field, for the core external interface, the ultimate security of the application server is to use the 1024-bit RSA algorithm. The RSA algorithm is currently also subject to great security threats.

Embodiment 1

[0052] In the embodiment of the present invention, the user terminal obtains the time stamp from the time stamp mechanism system, and uses WPKI to establish a secure data channel with the application server. The application server receives the time stamp sent by the user terminal through the secure data channel, and the application server verifies the time stamp through the time stamp mechanism system; during the verification of the time stamp After passing, the application server and the user terminal use the secure data channel for data transmission.

[0053] This embodiment provides a schematic diagram of the implementation principle of a mobile terminal identity authentication method based on WPKI and time stamps, as shown in figure 1 As shown, the specific processing flow is as follows figure 2 As shown, the following processing steps are included:

[0054] Step S210, the time stamp is authorized by the National Time Service Center and issued by an authoritative and cr...

Embodiment 2

[0079] This embodiment provides a kind of mobile terminal identity authentication system based on WPKI and time stamp, its specific structure is as follows image 3 As shown, it includes: user terminal, application server, time stamp mechanism system and OCSP server.

[0080] The user terminal is used to obtain the time stamp from the time stamp mechanism system, and establishes a secure data channel with the application server using the wireless public key infrastructure WPKI;

[0081] The application server is configured to receive the timestamp sent by the user terminal through the secure data channel, and the application server verifies the timestamp through the timestamp mechanism system; in the After passing the verification of the timestamp, use the secure data channel to transmit data with the user terminal;

[0082] The time stamp mechanism system is used to send the time stamp to the user terminal, and verify the time stamp sent by the application server.

Abstract

The embodiment of the invention provides an identity authentication method and an identity authentication system for a mobile terminal based on a WPKI and a timestamp. The method mainly comprises the steps that a user terminal acquires the timestamp from a timestamp mechanism system and establishes a safety data channel with an application server by adopting the WPKI; the application server receives the timestamp sent by the user terminal through the safety data channel and authenticates the timestamp through the timestamp mechanism system; after authentication of the timestamp is passed, data are transmitted between the application server and the user terminal by utilizing the safety data channel. According to the embodiment of the invention, a mobile intelligent terminal communicates with the application server by adopting a WPKI technology, and the safety of the whole link is guaranteed by adopting an SSL communication protocol based on an ECC algorithm; by using the timestamp service of a trusted third party, various attacks to a group key exchange protocol can be resisted, so that the effective identity authentication of the mobile terminal is achieved, and the data safety of wireless services of the mobile terminal is guaranteed.

Description

technical field [0001] The present invention relates to the technical field of media communication, in particular to a mobile terminal identity authentication method and system based on WPKI (Wireless Public Key Infrastructure, wireless public key infrastructure) and time stamp. Background technique [0002] There are three main types of mobile smart terminals, namely Google's android phones, Apple's iphones, and Microsoft's Windows Phones. Among them, the operating system of Android smartphones is based on the Linux kernel, which is a mobile phone operating system announced by Google. It was developed by Google in the early stage and later developed by the Open Handheld Devices Alliance. The platform consists of operating system, middleware, user interface and application software, and is the first truly open and complete mobile software for mobile terminals. [0003] WPKI is a set of standard key and certificate management platform system that introduces the PKI (Public K...
