Abstract: 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.

Abstract: Transmission of data between a download server and a communicating object through a communications network is initiated by a registration server, by transmitting connection parameters received from the download server to the communicating object via a first data channel opened by a first agent of the communicating object after attaching the object to the network. As a function of the connection parameters, a second agent in the communicating object opens a second data channel to the download server so as to transmit the data therein. As long as the first data channel is open, other servers can initiate a transmission via the registration server.
