Method and device for authenticating mobile terminal

Abstract

The invention discloses a method for authenticating a mobile terminal, comprising the following steps of: acquiring a digital certificate, an international mobile equipment identity number (IMEI), an international mobile subscriber identification number (IMSI) and short message service center (SMSC) number information on the mobile terminal; carrying out the encryption algorithm according to the IMEI, the IMSI and the SMSC number information to obtain a ciphertext; comparing the digital certificate with the ciphertext; and when the digital certificate is consistent with the ciphertext, passing the authentication. The invention also provides a corresponding device. According to the method and the device for authenticating the mobile terminal, by acquiring the IMEI, the IMSI and the SMSC number information on the mobile terminal, the mobile terminal is authenticated and the use safety of the mobile terminal on the internet can be improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for authenticating a mobile terminal. Background technique [0002] A digital certificate is a series of data that marks the identity information of each party in Internet communication, and it provides a way to verify identity on the Internet. The simplest digital certificate consists of a public key, name, and digital signature of a certificate authority. [0003] The digital certificate issuance process is generally as follows: the user first generates his own key pair, and transmits the public key and some personal identity information to the certification authority. After verifying the identity, the certification center will perform some necessary steps to make sure that the request is indeed sent by the user. Then, the certification center will issue a digital certificate to the user, which contains the user's personal information and public key inform...

Problems solved by technology

[0004] At present, the acquisition and use of digital certificates require user interaction and input of a large amount of personal user information, while mobile terminals cannot compare with personal computers in terms of processing power and communication capabilities, and the digital certificate mechanism on traditional personal computers cannot be used on mobile terminals. Work properly

Therefore, at present, the identity authentication of mobile terminal users on the Internet is mainly through simple authentication of the International Mobile Equipment Identity (IMEI) or the International Mobile Subscriber Identification Number (IMSI) or a combination of the two. This authentication method is simple. Easy to be cracked, easy to cause security risks
