Design of Secure System Architecture Model for Active Network
主动网络安全结构模型设计

In this paper, the assumption model and the threat model of active network security system are introduced. A secure system architecture model based on these models and security requirement is presented. Definition of secure system architecture model includes authentication, authorization, integrity and encryption. To protect the integrity of the contents of active packet, the encryption and the digital signatures can be employed and the authorization mechanisms or policies are defined and enforced to provide controlled access to the active node resources.
