A method is disclosed and includes determining a test plan to test a kernel on a mobile device, and determining an interaction input message according to the test plan, the interaction input message comprising first data. The method also includes transmitting the interaction input message comprising the first data to the mobile device over a network-based communication channel. The kernel in the mobile device generates the interaction output message in response to receiving the interaction input message. The method also includes receiving, from the mobile device, the interaction output message comprising second data from the mobile device over the network-based communication channel, and determining if the interaction output message is consistent with the test plan.

Network based testing of mobile device kernels system and method

Embodiments of the invention relate to a technique for updating a device comprising a first and second applets implementing application code. The technique may include determining that the application code needs to be updated, generating a verification value, and sending the verification value and updated code for a function in the first applet. The updated code for the function can be stored in the second applet instead of the first applet, and the function maps of the applets can be updated to reflect the address of the updated function. The updated code can then be executed using the updated function maps to perform a process.

Systems and methods for updatable applets

Embodiments of the invention relate to a device comprising a first and second applets implementing application code. The device is configured to determine that the application code needs to be updated, receive updated code for a function in the first applet, store the updated code for the function in the second applet instead of the first applet, and update the function maps of the applets. The updated code can then be executed using the updated function maps to perform a process.

Embodiments of the invention relate to a device comprising an updatable applet and a static applet. For some embodiments, a device is disclosed comprising a processor, one or more memories storing an updatable applet, and a static applet in communication with the updatable applet, wherein the device is configured to receive updates to the updatable applet. The updatable applet and static applet may be executed through an access control software element that may prevent unrestricted access between the applets.
