    摘要: A method for selecting an electronic module from a plurality of at least two modules (M1, M2, M3) capable of emitting messages simultaneously, includes the steps of sending a general query message (ACTIVALL) to the modules, and selecting (AFI, SELECT-ID) the module having responded first, the modules, on receiving a query message (ACTIVALL, ACTIV), determining a random time interval (P) and sending a responding message (ID, R) when the said time interval (P) has elapsed. A module is set in idle position (IDL) when it receives a message (MESS) before the time interval (P) preceding the sending of a response (ID, R) has elapsed. The idle position (IDL) is at least characterized by the fact that one module does not respond, subsequently, to a complementary query message (ACTIV). This invention is particularly useful for contactless smart card readers and for terminals for electronic labels.

    摘要: Encryption circuits and methods, in particular for smart cards, are disclosed. Smart cards without microprocessors may be authenticated very simply by using encryption with a secret card data table on which recursive cycles are executed. During each cycle, a word is read out of the table, said word being at an address that is at least partially defined by the word read out in the previous cycle. The new address preferably consists of several bits from the previous word and a bit from internal card data, external data supplied by a card reader, or a register containing a partial encryption result.

    摘要: The invention relates to a method for securing the execution of an onboard NFC application in a secure element which does not include a native OTA application. The secure element interacts with a mobile terminal including a removable card. According to the invention, the method includes recording an identifier of the removable card in the secure element no later than when the NFC application is loaded onto the secure element. When an event occurs, a verification is made, in the secure element, whether or not the identifier of the removable card present in the mobile terminal corresponds to the identifier previously stored in the secure element, in order to detect a possible change of the removable card.
