    A User Plane Security Protocol for ATM Networks (Extended Abstract)

    No full text
    Asynchronous Transfer Mode (ATM) has been identified as the transfer mode for implementing Broadband ISDN (BISDN), a universal network supporting different applications and customer categories. Many of these applications involve sensitive data or highly valuable information flows. Therefore, network security is one critical issue in offering ATM services. In this abstract, we first analyze the security requirements for ATM networks and identify the secure ATM protocol stack. Then, we propose a simple solution to enhance the user-plane security of ATM networks. Our solution utilizes the existing ATM signaling protocol (e.g., OA&M F5 cells) to e..
