Establishing a secure link on a second protocol between a secure element and a smart device via a link on a first protocol by establishing a link on the first protocol between the secure element and the smart device, and generating, by the secure element, a communication encryption key and associating a status with the encryption key and assigning the status a first level. Transmitting the key and the status of the key from the secure element to the smart device over the link on the first protocol. The secure element and the smart device are paired over the second protocol thereby establishing a second-protocol link. Transmitting a message encrypted using the key to the smart device over the second-protocol link. Upon verifying the cardholder as an authorized cardholder for the secure element, elevating the status of the communication encryption key from the first level to a second level.

Secure end-to-end pairing of secure element to mobile device

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.

Java card application memory footprint optimization

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; &#x2014;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.

Method for modifying the execution of a platform-independent method of an integrated circuit card

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:

Method of communicating between two devices

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.

Method and system for accessing a service

The invention relates to a personal token for a mobile telecommunication network, hosting application software. The personal token is operable to receive an over-the-air SMS message encapsulating commands directed to the application, open the SMS and extract the commands from the SMS. The steps of opening the SMS and extracting the commands from the SMS are performed by a software entity in the personal token which is distinct from the application, so that the software entity initiates transmission of the extracted commands to the application.

Personal token having enhanced communication abilities for a hosted application

The invention relates to a personal token storing a javacard application code lying over an area of the memory of the personal token, the personal token being able to run such javacard application so as to deliver HTML page data to an external device for the external device to display an HTML page on the basis of the such delivered HTML page data, said personal token further storing data to be used as a constructing part of the HTML page, characterized in that the data to be used as a contributing part of the HTML page are in at least one file which is separate from the memory area over which the Javacard application code is lying, and the personal token is programmed for opening the at least one file storing the contributing part of the HTML page when such data are requested for delivering said HTML page data to said external device.
