Securing the Node of an Active Network

摘要: Active networks aim to provide a software framework that enables network applications customize the processing of their communication packets. Security is critical importance success active networking. This thesis presents design and description implementation for securing node an using networking principles. The secure architecture includes operating system security API, guardian, quality protection (QoP) provisions. supports highly customized situational policies created by users dynamically. It permits nodes satisfy application-specific dynamic requirements. can fundamental base infrastructure. In addition architecture, this also analysis information flow type system. Information control concerned with right dissemination information. Secure properly restricts propagation sensitive cryptographic data beyond API untrusted environments. demonstrates ensure enforcement efficiently therefore additional assurance networks. We describe integration into two systems demonstrate its flexible innovative features present detailed performance results.
