Abstract: A touchpad includes at least one supporting plate and at least one flexible printed circuit fixed to the supporting plate. The supporting plate includes at least one first electrical protection track, made by a conductive ink, connected to at least one connection track with a predetermined value of potential and at least one connection track for connection towards a processor.

Abstract: A system is provided for protecting a signal within an electronic device. Such a system includes a connector and a printed circuit. The connector has a generally rectangular parallelepiped shape and includes: at its base, at least one solder termination corresponding to a contact region conveying the signal to be protected; and a slot for inserting a printed circuit. The printed circuit is housed in the insertion slot and shaped so that it covers the solder termination.

Abstract: A method is provided for creating a contextualized, digitized signature, which is representative of a signature made by a user on a signature input device for a given action. The method includes: obtaining at least one piece of data relative to a context; obtaining a signature, delivering a digitized signature; and combining the digitized signature and the at least one piece of context data, delivering the contextualized, digitized signature.

Abstract: A power supply base for a payment terminal is provided with a housing having an opening for receiving a memory card. The power supply base includes a guide for guiding the payment terminal towards a position wherein it can receive the power supply, the guide including at least one guiding part shaped in such a way as to enable the insertion thereof into the opening of the payment terminal.

Abstract: A method is provided for protecting an electronic terminal. The method includes: activating a state of monitoring the terminal; in the state of monitoring, detecting a manipulation of the terminal, generating the passage of the terminal to a so-called suspect state, representative of a risk of attempted fraudulent use of the terminal; in the suspect state, triggering a reaction by the terminal, the reaction of the terminal including updating an alert level representative of a probability of attempted fraudulent use of the terminal, and a implementing at least one reactive action dependent on the alert level.

Abstract: A method is provided for multiplexing messages exchanged between a payment terminal and a communication terminal via a connection between the payment terminal and the communication terminal using the iPod Accessory Protocol, iAP. The method includes: an initialization step of initializing an external communication interface with the communication terminal, a first transmission step of transmitting, to the communication terminal, a request for creation of remote virtual channels via the external communication interface; a creation step of creating, within the payment terminal, local virtual channels corresponding to the remote virtual channels; and a second transmission step of transmitting data frames associated with the local virtual channels via the external communication interface.

Abstract: 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.

Abstract: There is proposed a method of managing an array of keys by a device, each key pressed short-circuiting a row and a column of the array. During at least part of a time slot lying between two successive iterations of a sweep phase, the device performs a first protection mechanism, including reading a logic value on at least one row or column, and detecting an attempted illicit sweep as a function of the logic value read, and/or a second protection mechanism, including writing an arbitrary logic value, equal to or different from the predetermined logic value, on at least one row or column, so as to prevent an attempted illicit sweep.

Abstract: A protection device is provided, which includes a detection circuit for detecting a short-circuit between at least two output branches of a magnetic reading head. Each of the output branches is able to convey a signal read by the reading head on a track of a magnetic card and the detection circuit is able to detect a short-circuit during the reading of at least one track of a magnetic card.
