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

Abstract

The invention discloses a mobile terminal uniqueness authentication method based on a software digital certificate, which belongs to the technical field of computer and information security, and is specifically as follows: (1) The mobile terminal installs a security client, generates a certificate request associated with device information, and sends a request to the server register. The server issues a digital certificate to the mobile terminal to realize the association between the digital certificate and the device. (2) When in use, the server sends random information to the mobile terminal, the security client receives the information, uses the private key of the digital certificate of the machine to sign the random information, and sends the signed data to the server. The application server uses the digital certificate public key to verify the signature and confirm the identity of the communication peer. The invention can well verify the mobile terminal, and enhances the strength of the verification without adding hardware verification devices.

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...
