Abstract: The present invention relates to a method for protecting a payment terminal, comprising: —a data encryption key; —a monitoring module comprising a means for measuring a physical parameter; —a counter unit of a microcontroller, the counter unit being slaved to a clock for incrementing a counter value; said method comprising the steps of: —measuring a physical parameter by the means for measuring the monitoring device; comparing the measured value with a predetermined threshold value corresponding to a physical attack; —resetting the counter unit; and if one of the following conditions is met: ?at least one physical parameter value is indicative of a physical attack on said terminal; ?the counter value is greater than a predefined threshold value; the method also comprises a step of removing access to the encryption key.

Abstract: Secure management of electronic transactions is provided by a system server that is communicatively coupled to terminals configured as thin client devices (TCD) and to one or more application servers. A TCD completes a secure communications link with the system server, and transfers information concerning the identity of a user and account information from a secure transaction card (STC). Upon authentication, the system server drives the display of available applications at the TCD, allowing the user to select and engage in a desired transaction with the application server hosting the selected application. During the transaction, the system server brokers communications according to the different security schemes used by the TCD and the application server and, ultimately, stores a transaction ticket that memorializes the transaction. The transaction ticket can later be retrieved by presenting appropriate authentication information.
