METHOD AND SYSTEM FOR DYNAMICALLY ESTABLISHING ENCRYPTED TUNNELS ON CONSTRAINED-BAND NETWORKS

摘要

THE INVENTION RELATES TO A METHOD AND A SYSTEM ARCHITECTURE MAKING IT POSSIBLE TO ESTABLISH IN A DYNAMIC MANNER ONE OR MORE ENCRYPTED TUNNELS ON CONSTRAINED-BAND COMMUNICATION NETWORKS. IT MAKES IT POSSIBLE IN PARTICULAR TO ENCRYPT ONE OR MORE DATA STREAMS WHILE GUARANTEEING THE QUALITY OF SERVICES ON THE CONSTRAINED-BAND SYSTEMS, IN PARTICULAR FOR ENCRYPTED STREAMS OF VOICE OVER IP TYPE (INTERNET PROTOCOL) OR OF DATA TYPE. THESE TUNNELS ARE THUS ADAPTED MOST SUITABLY TO THE USEFUL DATA STREAMS WHILE MAKING IT POSSIBLE TO CONTROL AND ASSIGN THE NECESSARY VALUES FOR THE QUALITY OF SERVICE OR QOS ON THESE NETWORKS FIGURE 5
