Abstract

The invention discloses a mobile terminal intelligent card based data transmission method and a mobile terminal so as to solve a problem of secret key leakage existing in the prior art. The method comprises the steps that an intelligent card receives data transmitted by an application program in the mobile terminal; operating instruction codes contained in the transmitted data are acquired, and corresponding operations are carried out according to the types of the operating instruction codes. When the operating instruction codes comprise a decryption/ signature verification type of instruction code, decryption/signature verification is carried out on the transmitted data by using a pre-stored secret key, and then the transmitted data is provided for the application program; or when the operating instruction codes comprise an encryption/ signing type of instruction code, encryption/signing is carried out on the transmitted data by using the pre-stored secret key, and then the transmitted data is provided for the application program. The intelligent card and the application program are communicated through at least one of the following interfaces: an application program interface used for storing/reading short messages, an application program interface used for writing/reading an address list, an application program interface used for accessing to a GP card, an application program interface used for writing or reading an SIM card short message center and an application program interface used for reading STK menu data.

Description

Technical field [0001] The invention relates to the field of computer technology, in particular to a data transmission method based on a mobile terminal smart card and a mobile terminal. Background technique [0002] With the widespread popularity of mobile terminals, more and more users are accustomed to transmitting various types of data through mobile terminals such as mobile phones. For example, the user can use the mobile banking function provided by the mobile terminal to perform data transmission with the bank server, thereby completing various functions such as online transfer and payment, which provides users with many conveniences. [0003] However, when data is transmitted between the mobile terminal and a remote server (such as a bank server), some sensitive data (such as bank account numbers, passwords, etc.) are easily intercepted by illegal elements such as hackers during the transmission process, thereby threatening user account security. For this reason, in the pr...
