Abstract: This invention concerns a computer communication method using asynchronous messages in a distributed software architecture, for example of type AAA-MOM (Agent Anytime Anywhere - Messages Oriented Middleware), including a disconnectable platform such as a smartcard. This communication is carried out between firstly a card agent (CA), stored in a removable platform (31, 32), connectable to a terminal (21, 22), and secondly at least one standard software agent (AS). This standard agent can be stored in this computer network (1), in another renmovable platform. A message sent by the card agent (CA) to a standard agent (AS) or sent by a standard agent AS) to the card agent (CA), is stored in the network by at least one intermediate agent (CEPA,CAPA) managing the communications of this card agent (CA) with network (1).

Abstract: This invention concerns an iterative procedure for conversion of structured software objects into a raw data stream and vice versa, providing for their direct transfer using simple communication resources such as those of an embedded computer station, and reset of said software objects or reutilisation of memory space allocated to them. This procedure can be used by an embedded platform (2) or a portable object including at least a processor capable of exchanging information with a terminal in the form of linear data sequences. The procedure includes a step for conversion of a data set, in one direction or the other, between a linear data sequence arrangement on the one hand, and a structured arrangement describing or representing an object-oriented software object on the other hand.
