Abstract: The disclosure concerns a method of replacing a current key in a security element co-operating with a terminal in a network operated by a network operator, the method includes trying to decrypt the encrypted message by using the current key; selecting in a table stored in the secure element another key and try to decrypt the encrypted message by using the other key; replacing atomically the current key by the rescue key and do not use the current key anymore, the rescue key replacing the current key and, otherwise, try to decrypt the encrypted message by using another rescue key of the window if such another rescue key exists, until all rescue keys have been selected and used for decrypting the encrypted message and, if none of the rescue keys permit to decrypt the encrypted message, select the blocking key; and blocking the corresponding functionality of the security element.

Abstract: A slave wireless device includes several applications, a wireless communication interface and a processing module. The processing module interprets a presentation request and time-slotted markers received on the communication interface, selects several applications or application groups corresponding to the presentation request, and transmits the wireless slave device identifier distinctive for each application or application group selected in the distinctive time slot in response to the presentation request. The slave device is thus enabled to indicate several application groups in response to a single presentation request.

Abstract: The invention relates to a slave wireless device (Picc) comprising: several applications, a wireless communication interface, a processing module interpreting a presentation request (ReqB4SM00) and time-slotted markers (ReqB4SM00, SM2, SM3, SM4) received on the communication interface, selecting several applications or application groups corresponding to the presentation request (ReqB4SM00), transmitting the wireless slave device identifier distinctive for each application or application group selected in the distinctive time slot in response to the presentation request. Said invention enables the slave device to indicate several application groups in response to a single presentation request.

Abstract: The invention relates to the operational maintenance of an intelligent portable object (1) which is provided with a processing unit (6) having at least two communication and/or feed interfaces either with or without contacts. The method comprises a reinitialization step (MaZ) for the processing unit (6). The method is characterized in that it comprises at least one delay and/or reinitialization simulation step if a communication or application is in the process of being processed by the processing unit. The invention also relates to an associated device.

Abstract: The invention concerns a telecommunication terminal (2) comprising means to be accessed by a telecommunication network and means to be accessed by a micro-computer type processing unit (1), said terminal comprising a chip card (3) for implementing at least one application and logic means (I) for the card to be accessed by the network, said terminal further comprising logic means (I) to access the card (3) from the microcomputer (1) and means for managing (20) accesses coming from the telecommunication network and/or the microcomputer.
