Embodiment Construction

[0023] figure 1 A shows an embedded device D communicating a threat event ET from a Java Card JC platform to an applet via an interface device IM according to an embodiment of the present invention. The embedded device D includes a Java Card JC platform including a Java Card virtual machine JCVM, hardware HW and applets that the JC platform can communicate with. Device D can contain multiple applets. The hardware HW comprises a threat detection device DET incorporated as a light sensor, installed to detect attacks ATT via flashes of light etc. The JC platform and the applet each contain a corresponding part of the interface device IM between the JC platform and the applet. The interface means IM can be, for example, an application programming interface (proprietary, or a standard combined with specific parameters) API, or an exception mechanism.

[0024] exist figure 1 In the communication event of A, the light sensor DET of the embedded device D detects the flash attack A...

Abstract

An embedded device incorporating Java Card technology including a Java Card platform and at least one applet, and including both platform security features and applet security features. The device hasa) a threat detection means to detect events of threat (ET) occurring at the embedded device (D); and b) an interface means (IM) constructed to receive a threat notification (NOT) on a detected eventof threat (ET); and establish or use a communication channel (CH) between the platform and the applet and exchange threat (TI) information on the detected event of threat (ET) between the platform and the applet.

Description

technical field [0001] The present invention relates to embedded devices based on the Java card platform, such as smart card processor devices of a smart card form factor or other form factors other than cards, in particular SIM cards (SIM = Subscriber Identity Module), embedded SIMs, Payment cards, identity cards, all of these are incorporated into the Java Card platform. Background technique [0002] Embedded devices contain a runtime environment that runs on the device, and applets that provide device applet-specific services to users. For example, a payment applet that provides payment services, a SIM applet that provides mobile network-specific services, an identity applet that provides identity services, etc. [0003] A Java Card applet is installed into a Java Card embedded device, where a Java Card CAP file containing the applet code and further content required for the applet installation is loaded into the device, and then the contents of the CAP file continue in ...
