Abstract: A device (D) is dedicated to the interconnection between communication equipment (EC), equipped with a very short-range radio communication module (MCR) and a communication network (RC). This device (D) comprises i) relay means (MR) operative to relay received data to and from coupling means (MCP) coupled to said communication network (RC) and ii) an antenna (AN) capable, firstly, of radiating, or respectively capturing, very short-range electromagnetic waves, which are representative of data, to the, or respectively from the, radio communication module (MCR) whenever the communication equipment is placed within its immediate vicinity, and secondly, coupled to the relay means (MR) in order to transmit to them the data to be relayed coming from the radio communication module (MCR), and to receive from them (MR) the relayed data that comes from the coupling means (MCP).

Abstract: In a method of securing communication between a first software element and a second software element via a non-secure communication channel in collaboration with a security server, data carried by the communication channel is sent using a method of a security object supplied by the security server.
