Abstract

The invention discloses an authentication method and device of a subscriber identity module card and a nonvolatile storage medium. The method comprises the following steps: receiving an authentication request which is initiated by a mobile terminal and is used for authenticating a subscriber identity module card, and the authentication request comprises an encryption certificate of the mobile terminal; obtaining a timestamp generated by the timestamp server, and encrypting the timestamp by using a public key obtained by analyzing the encryption certificate of the mobile terminal to obtain a ciphertext timestamp; sending the ciphertext timestamp and an encryption certificate of the server to the mobile terminal; authentication information sent by the mobile terminal is received, the user identity identification card is authenticated according to the authentication information, and the authentication information is obtained by the mobile terminal based on the information of the user identity identification card, the encryption certificate of the server and the ciphertext timestamp. The technical problems of low verification intensity and low safety coefficient of the existing SIM card authentication technology are solved.

Description

technical field [0001] The present application relates to the field of chip security, in particular, to an authentication method and device for a user identification card, and a non-volatile storage medium. Background technique [0002] Subscriber Identity Module (SIM), also known as a super SIM card, is based on the SIM card security chip, using different functional modules of the SIM card to achieve low, medium and high levels of authentication security products, which can provide users with mobile phone-based One-click login of number, financial USB-Shield authentication, electronic identity authentication and other capabilities. [0003] The existing SIM card authentication method is to send the mobile phone number corresponding to the SIM card to the server for verification through the traffic channel, which has low verification strength and low safety factor. [0004] For the above problems, no effective solution has been proposed yet. Contents of the invention [...
