Processing devices, methods and non-transitory computer-readable media for processing data are disclosed. The data comes from a contactless memory card. The device has at least one contactless memory card reader. Such a device also has: a keyboard for acquiring input data coming from an input peripheral; a processor for processing at least one sequence of a remote transaction initialized on the basis of data coming from a contactless card; and a switch or a cell for selecting a mode of operation that has at least two states. The at least two states are: a state, called an inactivation state, in which the processor and the at least one memory card reader are inactive; and a state, called an activation state, in which the processor is active and in which the input data entered through the input peripheral are controlled by the processor.

Device for processing data from a contactless smart card, method and corresponding computer program

A method is provided for verifying an authenticity of a payment terminal, implemented by using of a device for verifying authenticity. The method includes: transmitting to the payment terminal a request for obtaining a piece of identification data by using of a contactless communications interface; receiving a response, through said contactless communications interface and coming from the payment terminal, to said request for obtaining a piece of identification data; comparing a field of said response with at least one piece of pre-recorded identification data; when the field includes a piece of identification data identical to said at least one piece of pre-recorded identification data, for issuing an assertion of authenticity of said payment terminal; when the field comprises a piece of identification data different from said at least one piece of pre-recorded identification data, issuing a piece of information on absence of authentication of the payment terminal.

Method for verifying the authenticity of a terminal, corresponding device and program

A method is provided for securing a microprocessor containing at least one main program, which operates with at least one memory. The method includes implementing counter-measures, during which additional operations, that are not required for the main program, are implemented so as to modify the consumption of current and/or the processing time of the microprocessor. The method also includes: identification of at least one address or one memory zone of the memory(ies), called critical addresses, and which contain, or which may contain, critical data for said main program; monitoring the addressing ports of the memory(ies), so as to detect the access to the critical address(es); and activation of the step of implementing counter-measures, when an access to the critical address(es) is detected.

Method for securing a microprocessor, corresponding computer program and device

A countermeasure method for a microcontroller that executes sequences of instructions. The instructions are executed according to a pipeline method. At least one waiting time is randomly introduced between two consecutive instructions and/or within at least one instruction. The method is implemented by the electronics of the microcontroller rather than by software addition.
