Abstract: Disclosed is a secure element used in a host terminal, including several communication interfaces for communication with the outside, several applications and a runtime environment. At least two applications are issuer security domains instantiating two GlobalPlatform configurations, typically GP configurations UICC and eSE. The runtime environment is configured to receive a command over a communication interface, to determine a target application for executing that command according to that communication interface and to send, over that same interface, a response to the command. This ensures the independence of the two configurations by providing that the runtime environment only authorizes access to an application resource of the secure element for executing the command by the target application if that application resource is associated with the communication interface for receiving the command.

Abstract: A method for performing a secure transaction between a secure device (2) and a terminal (4), the method being carried out by the secure device (2) and comprising the steps of: receiving transaction data from the terminal (4), characterized in that it comprises, before the step of receiving transaction data from the terminal (4), the steps of obtaining transaction data entered by a user of the secure device (2), and transmitting the transaction data to the terminal (4).

Abstract: The present invention relates to the field of debugging of compiled programs in a hardware security module such as a microprocessor card. A module according to the invention includes a microprocessor and a compiled program to be executed by the microprocessor in order to carry out an operation. The compiled program includes at least one debugging instruction which whether or not it is executed does not modify the execution of the operation. And, the hardware security module includes an element of inhibiting or activating the debugging instruction during the execution of the compiled program.

Abstract: The present invention relates to the field of processing within hardware security modules, such as for example debugging of compiled programs. A debugging module includes a microprocessor and a compiled program to be executed by the microprocessor in order to carry out an operation, and is configured to exchange with an external entity, in a master/slave mode, messages relating to the operation. The compiled program includes at least one debugging instruction which whether or not it is executed does not modify the execution of the operation. The hardware security module is moreover configured to transmit, during the execution of the compiled program, data generated, for example by the debugging instruction, over a communication channel initiated by the hardware security module, to an entity external to the hardware security module.
