Problems solved by technology

Usually, the card issuers of the joint card issuer are in a cooperative relationship with each other, and the authority applications are equal. Therefore, the card issuer of the joint card issuer does not want any party to be in charge of the ISD, and hopes that their applications are only controlled by their own security domain. For such applications scenario, the standard GP specification cannot meet this requirement

Embodiment Construction

[0058] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the embodiments and accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.

[0059] The specific embodiment of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0060] refer to figure 1 As shown, the security control method on the smart card terminal side of the embodiment of the present invention includes the following steps:

[0061] Step S101, initiate an authentication request to the ISD of the smart card.

[0062] Step S102, receiving the authentication result returned by the ISD. Wherein, the authentication result is usually a return code.

[0063] Step S103, when the authentication result is a succ...

Abstract

The present invention provides a smart card and its security control method, device and system. The method includes: the smart card terminal sends a shielding ISD instruction to the ISD of the smart card after the authentication is successful; Relevant handover to each ESSD of the smart card for separate management; each of the ESSDs takes over the management authority of the ISD handover, and after taking over, the management authority of each of the ESSDs is limited to this security domain and all applications mounted under it; When receiving any command, each ESSD processes the command according to its own management authority. The present invention realizes that each card issuer of joint card issuance can control its own application only by its own security domain, thus improving the data security of each card issuer of joint card issuer.

Description

technical field [0001] The invention relates to the security control technology of smart cards, in particular to a smart card and its security control method, device and system. Background technique [0002] The Global Platform specification (hereinafter referred to as the GP specification) is an international general smart card behavior management specification. All Java Cards follow the GP specification. In the GP specification, the issuer security domain (ISD, Issuer Security Domain) has the highest management authority, such as global delete (Global Delete), token verification (Token Verification), card life cycle status, etc., among which, ISD is also called as the primary security domain. [0003] At present, there are many scenarios of joint issuance of cards by multiple applications in China. The GP specification provides a supplementary security domain (SSD, Supplementary Security Domain) function for multiple application scenarios. Each application can be mounte...
