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). At t...

Abstract

The invention provides a method for production and authentication of a telecommunication smart card, which comprises (1) determining a telecommunication smart card identification parameter, and generating a first encryption key according to specific value of the identification parameter and production amount; (2) producing a telecommunication smart card and downloading a telecommunication smart card operating system to the card; (3) initiating the telecommunication smart card, performing individual treatment, inputting the specific values of the identification parameter, production amount and the first encryption key to a production equipment, generating a second encryption key by the operating system, determining whether the first encryption key is same as the second encryption key, and if yes, recording the specific value of the identification parameter and production amount; (4) the telecommunication smart card receiving an authentication command, calculating the range of the identification parameter, and determining whether the authentication is in the range, if yes, returning a correct authentication value. The invention can effectively control the downloading amount of the telecommunication smart card operating system, so as to effectively protect the copyright of the telecommunication smart card operating system.

Description

technical field [0001] The invention relates to a production and authentication method of a telecommunication smart card, in particular to a production and authentication method of a telecommunication smart card which can effectively protect the copyright of the telecommunication smart card operating system. Background technique [0002] With the popularization and application of smart cards, smart cards have been widely used in mobile communications, e-commerce and other fields, among which the more common ones are telecom smart cards that are installed on mobile phones and communicate through wireless communication networks, such as SIM cards (Subscriber Identity Model, Subscriber Identity Module ). [0003] The production process of the existing SIM card generally includes the following steps: First, the card of the SIM card is produced, that is, the hardware part of the SIM card is produced, including the central processing unit and memory of the SIM card, but no informa...
