Embodiment Construction

[0039] In order to make the objectives, technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that the embodiments in the application and the features in the embodiments can be combined with each other arbitrarily if there is no conflict.

[0040] The machine-card interlocking method provided by the embodiment of the present invention is specifically applied to a scenario where a terminal and a SIM card are interlocked, where the terminal may be a mobile terminal, for example, a digital mobile phone or a smart phone. The machine-card interlocking method provided in this embodiment can be executed by a machine-card interlocking device. The machine-card interlocking device can be set separately or in a terminal or a SIM card, where the device can be implemented by software / hardware. The machine-card interlocking method and its d...

Abstract

The invention discloses a terminal-card interlocking method and a terminal-card interlocking device. The terminal-card interlocking method comprises steps that a terminal is used to acquire a first code transmitted by an SIM card; the terminal is used for encryption calculation of the first code and a second code to acquire an encryption result, and the second code comprises an integrated circuit card identification code; the terminal is used to transmit the encryption result to the SIM card, and then whether the SIM card and the terminal are interlocked with each other is determined by the SIM card. Normal communication is realized in a scene of matching the SIM card and the terminal, and therefore the function of interlocking the SIM card and the terminal is realized.

Description

Technical field [0001] The invention relates to the field of communication, in particular to a machine-card interlocking method and device. Background technique [0002] With the development of communication technology, people can use the machine-card interlocking method to realize that a machine-card can only be used on one terminal. [0003] Generally, after a machine card, such as a Subscriber Identity Module (SIM) card is set in the terminal, an initialization operation is performed between the SIM card and the terminal, so that the terminal can obtain the personal identification code (Personal Identification Password) set on the SIM card. Number, PIN for short), where the PIN code is set by the SIM card at the factory. Then, the terminal modifies the obtained PIN code to a random value, and saves the random PIN code in the terminal, and then activates the SIM card Therefore, each time the terminal is turned on, the terminal can verify the SIM card with the random PIN code to ...
