Embodiment Construction
[0018] see image 3 , image 3 It is a flowchart of an embodiment of the present invention. The telecom smart card in this embodiment is a SIM card. First, the developer of the SIM card operating system determines a parameter that uniquely identifies the SIM card. In this embodiment, the parameter is an ICCID number. The ICCID number is provided by the communication operator, and each SIM card has a unique ICCID number to distinguish different SIM cards.
[0019] When a SIM card manufacturer needs to produce in batches, it first needs to apply to the operator for the ICCID number of the batch of SIM cards, and then inform the SIM card operating system developer of the initial ICCID number and production quantity of the batch of SIM cards. The developer will use the initial ICCID number as the specific value of the SIM card identification parameter, and according to the initial ICCID number and production quantity, generate the first key through an algorithm (step S1).
