Embodiment Construction

[0016] Illustrative examples of the invention will now be described with reference to the drawings, wherein like reference numerals refer to like elements. The embodiments described below are intended to help those skilled in the art to fully understand the present invention, and are intended to be illustrative rather than limiting.

[0017] figure 1 is a smart card according to an example of the present invention. The construction process of the smart card is similar to that of a conventional smart card, and will not be repeated here. The smart card includes different application modules, such as application module 1 , application module 2 and application module 3 , an associated record setting module 20 , and a key management module 30 .

[0018] Each application module in the smart card performs different functions, for example, application module 1 is used for traffic payment, application module 2 is used for merchant points, and application module 3 is used for parking ...

Abstract

The present invention provides a key management method for smart cards, the method includes setting associated records for each of the different applications of the smart card, wherein each application corresponds to at least one associated record; and using a key for each associated record management mechanism.

Description

technical field [0001] The present invention relates to the key technology of the smart card, more specifically, to the key management of the application of the smart card. Background technique [0002] The application of IC smart card has been very popular. Since the use of IC smart cards often involves functions such as payment or the private information of cardholders, an encryption mechanism is usually used for the contents of the IC smart cards. [0003] As far as conventional IC smart card encryption is concerned, the key is generally applied at the application or file layer of the smart card. For example, if smart card A includes payment application A and payment application B, key management must be implemented for payment application A and payment application B respectively, that is to say, payment application A implements key management for A, and payment application B implements key management for B's key management. [0004] If payment application A and paymen...
