Abstract: A method for providing secure communication between first and second systems connected to the internet includes assigning respective permanent internet addresses to first and second entities associated with the systems, making at least one application located in a server of said second system accessible to the first entity, and encrypting data exchanged between the first and second entities in conformity with a desired security protocol. The first and second systems each include a communication protocol stack having at least one layer which allows for the encrypting step to be performed. Through this method, a user in the first system can directly address an application hosted by the second system without using or even knowing the name of the host system. The entity in the first system may be a wireless unit operating, for example, in GSM and the entity in the second system may be a server in an intranet.

Abstract: The invention relates to a communication process via an internet network that comprises distributed systems (S1). Each system (S1) is connected to the network (SRX) via a standard interface module (10), standard software layers (12, 13) comprising a stack of addresses and protocols, and hosts software entities (SVA, SVB). The latter and the systems (S1) are provided with a network address in a virtual subnetwork to which the system itself (S1) and said software entities (SVA, SVB) are connected via a specific interface module (11, 20, 30) and specific software layers (21-22, 31-32) comprising a stack of addresses and protocols. The addresses and names of the systems (S1) and of the software entities (SVA, SVB) connected to the virtual networks (SVNy) are stored in a domain name directory (DNS1), making it possible to directly address one of the software entities (SVA, SVB).
