Network Responsibilities Identified Research And Implementation

As the development of the computer technology and Internet, people begin to run all kinds of activities on the Internet, such as e-commerce, e-governance, digital multimedia online sharing and so on.. Security frameworks and software provide the foundation for Internet application. A unified national Certificate Authority (CA) provides security in e-commerce. If there is no responsibility cognizance technology based on the CA, it will be difficult to solve security problems which cause losses in e-commerce. It has seriously hampered the development of electronic commerce. The difficult to trace people's activities in the network causes people to untrusting. Fraud and so many of false information are another problem of network. It urgently needs the effectively Responsibility Cognizance Technology to solve these problems. To ensure a orderly development of the Internet, we need to do some In-depth study about the Responsibility Cognizance technology based on web.The dissertation studies the technology of the Responsibility Cognizance. The main contributions of the dissertation are summarized as follows:(1)The conception of non-repudiation, auditability, accountability are given based on electronic authentication, electronic evidence, The definition for web-based Responsibility Cognizance is presented.(2)A third-party witness method is proposed to perform the Responsibility Cognizance. By studying the time-stamp protocol and evidence-preservation this dissertation proposes a safety electronic witness protocol. It provides a possible solution for building a Responsibility Cognizance system.(3) Some Responsibility Cognizance frameworks for different scenes, such as a security transaction model that include responsibility cognizance, the content delivery systems of auditability, security distribution method for digital works, are proposed. It also does some software development to validate these proposals.
