Abstract: The invention is a method of communicating between a caller device and an executor device wherein the executor device comprises a memory having a layout which defines formats and addresses used for storing data in the memory. The executor device comprises an application including a service and the method comprises the steps of: providing the caller device with the layout and an indicator reflecting the service during the handshake phase, sending to the executor device a data block corresponding to a command targeting the service, wherein the data block complies with the layout and is devoid of metadata, sending to the caller device a response block which complies with the layout and which corresponds to a result generated by execution of the command.

Abstract: To access a service, each user device stores one first key. The user device is connected to a first server. A terminal sends to a second server a connection request. The second server responds with first data relating to a transaction identifier and an associated challenge. The terminal determines a first result depending upon the first data and the first key. The terminal sends to the first server the first result and user device data. The first server identifies a user device based upon the user device data and sends to the device the first result. The device determines the challenge and the transaction identifier based upon the first result and the first key and sends to the second server the challenge and the transaction identifier. The second server verifies whether the data received from the device matches the first data and, if so, authorizes the terminal to connect.

Abstract: There is described a method for Java Card application memory footprint optimization which relies on the separation in advance of the code related to the personalization from the rest of the code. It allows this code to perform the personalization of an application installed from a main package while being itself included and installed from a separated package dedicated to the personalization, namely the Card Personalization Specifications (CPS) package. This way, the CPS package and all the code inherent to the personalization can be removed once all the personalization steps have been completed.

Abstract: Modification of the execution of a platform-independent first method of an application within an integrated circuit card having a first non-volatile memory, a second rewritable non-volatile memory, a virtual machine and a processor unit, wherein said platform-independent first method includes a first operations sequence and a second operations sequence. Checking if there is a call within said platform-independent first method to a specific second method, having one parameter; —if there is such a call and if said specific second method is not platform-independent, checking if there is an alternate function associated to said platform-independent first method stored in a memory of said integrated circuit card; if there is an associated alternate function: executing said alternate function to replace said first operations sequence; executing the second operations sequence of said platform-independent first method; otherwise executing by the first operations sequence and the second operations sequence of said platform-independent first method.
