Abstract随着计算机技术、网络应用的发展,人们开始在虚拟世界中完成各种活动,如电子商务、政务、网络多媒体数字信息共享等。各种安全框架和软件为网络活动提供了良好的基础。在电子商务中,统一的、全国性的认证中心保障了电子商务安全。但是如果没有相应的基于认证中心的责任认定体系,当电子商务中出现造成损失的安全问题时,这些安全问题将难以解决,会严重制约电子商务的发展。由于人们在网络中的行为难以有效的追踪,导致人们对网络的信任程度下降。网络欺诈和大量的虚假信息是互联网的另一问题。因此当前急切需要有效的责任认定技术来解决网络中遇到的这些问题。为保证互联网有序良好的发展,需要对网络世界中的责任认定技术做深入地研究。 本文围绕国内外与网络责任相关的研究做出分析总结.其主要贡献总结如下: (1)通过分析和研究抗抵赖性、可审计性、可追溯性,以及电子认证、电子证据等一些关键技术,对广义的网络责任定和狭义的责任认定内涵给予了阐述,并界定其外延。 (2)在研究了时间戳和证据保全技术的基础上,提出了电子见证协议。该协议为构建网络责任认定体系提供了一种可能的解决方案。 (3)针对具备的应用场景,提出了不同形式的责任认定的框架。如电子商务中的包含责任认定功能的安全交易模型、可追溯的网络内容发布体系、数字媒体版权保护方法。并对该框架做了部分验证性开发。
Other AbstractAs the development of the computer technology and Internet, people began to run all kinds of activities on the Internet, such as e-commerce, e-governance, digital multimedia online sharing et al. Security frameworks and software provide the foundation for internet application. A unified national Certificate Authority (CA) provides security in e-commerce. If there were no responsibility cognizance technology based on the CA, it would be difficult to solve security problems which commerce and cause losses in e-commerce. It seriously hampered the development of electronic commerce. The difficult to trace people’s activities in the network caused people to untrusting. Fraud and so many of false information is another problem of network. It is urgently to find 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 work of this dissertation is mainly focused on the studies of Responsibility cognizance technology. The main contributions of the paper are summarized as follows: (1) In analysis and study of the concept for non-repudiation, Auditability, Accountability, based on electronic authentication, electronic evidence, and the paper give the definition for web-based Responsibility Cognizance. (2)A third-party witness method is proposed to perform the Responsibility Cognizance. By studying the time-stamp protocol and evidence-preservation this paper propose a safety electronic witness protocol. This 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 work to validate those proposals.
