Problems solved by technology

Although this method is simple and easy to implement, it is weak in security, and the text messages and verification codes sent are easy to be stolen. There is also SIM duplication and counterfeiting technology, which makes information and communication no secret at all.
[0004] (2) Use special hardware devices, such as SD cards with computing functions, SIM cards, etc. This method has high security, but the user cost increases and the compatibility of mobile terminals is limited

Embodiment Construction

[0044] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0045] The mobile terminal unique authentication method based on the software digital certificate provided by the present invention is mainly divided into a mobile terminal registration part and a mobile terminal authentication part.

[0046] Wherein mobile terminal registration comprises the following steps:

[0047] (11) Generate a public-private key pair in the mobile terminal, and use the mobile terminal device information as a request item to generate a certificate request, and then send the certificate request to the application server for registration.

[0048] see figure 1 , this step can be implemented by installing a customized security client in the mobile terminal, and the security client generates a public-private key pair. The pu...

Abstract

The invention discloses an authentication method of mobile terminal uniqueness based on a software digital certificate, and belongs to the technical field of computers and information safety. The method specifically comprises the following steps: (1), a safe client side is installed on a mobile terminal, a certificate request relevant to equipment information is generated so as to be registered by a server side; a digital certificate is issued to the mobile terminal by the server side, and relevance between the digital certificate and the equipment is achieved. (2), when the method is used, random information is sent to the mobile terminal by the server side, the information is received by the safe client side, the random information is signed by using a private key of the digital certificate of the equipment, and the signing data are sent to the server side. The signature is verified by a public key of the digital certificate by an application server, and a communication opposite terminal identity is confirmed. The method is capable of verifying the mobile terminal commendably and enhancing intensity of authentication on the basis that hardware authentication equipment is not added.

Description

technical field [0001] The invention belongs to the technical field of computer and information security, and in particular relates to a method for authenticating a mobile terminal in the mobile Internet. Background technique [0002] With the rapid development of the mobile Internet, security issues are facing challenges. How to effectively authenticate mobile terminals is the focus of attention. There are currently several authentication methods: [0003] (1) Use text messages and verification codes. Although this method is simple and easy to implement, it is weak in security, and the text messages and verification codes sent are easy to be stolen, and there is SIM duplication and counterfeiting technology, which makes information and communication no secret at all. [0004] (2) Use special hardware devices, such as SD cards with computing functions, SIM cards, etc. This method has high security, but the user cost increases and the compatibility of mobile terminals is lim...
