Embodiment Construction

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0026] The method provided by the embodiment of the present invention can be applied in a smart card, and specifically can be applied in a JAVA card. In this case, the Applet 1 and Applet 2 It can be two Applets in different security domains in the JAVA card.

[0027] The embodiment of the present invention provides a method for invoking a JAVA card object, such as figure 1 shown, including:

[0028] 101. Applet 1 Send a service request message to JCRE, th...

Abstract

Embodiments of the present invention disclose a JAVA card object calling method and apparatus, relate to the smart card field, and are used to improve security of interaction between Applets in a JAVA card. The method comprises: receiving, by a JCRE, a service request message sent by an application program Applet1; acquiring, by the JCRE, interaction information between the Applet1 and an Applet2 according to an identity of the Applet1 and an identity of the Applet2; acquiring, by the JCRE, credibility between the Applet1 and the Applet2 according to interaction information between the Applet1 and the Applet2, wherein one interaction information comprises service level information of the interaction and information about whether a service request task of the Applet1 succeeds after the interaction; and when the credibility meets a credibility threshold, determining, by the JCRE, that the Applet1 calls a shared interface service of the Applet2.

Description

technical field [0001] The invention relates to the field of smart cards, in particular to a JAVA card object calling method and device. Background technique [0002] The storage area in the JAVA card is divided into different security domains. A security domain corresponds to a collection of objects of a type, and the collections are isolated by firewalls. Access between objects in a collection is legal, and access between objects in different collections is conditional. This cross-collection object access rule is called a shared interface object access mechanism. [0003] When the first Applet (application program) in a collection calls the shared interface service of the second Applet in another collection, the first Applet sends a shared interface service request message to the second Applet by JCRE (JavaCardRuntimeEnvironment, JAVA card runtime environment) , the second Applet verifies whether the shared interface service is opened according to a preset rule, and if th...
