Networked Collaborative Design Data Security Policy

As animportant branch of CSCW, CSCD has attached more and more attractiveness to research institutions and industry. Based on information system security architecture of the basic theory and the system properties of collaborative design system, this thesis focused on meeting Information security and confidentiality, integrity, identity certainty and non-repudiation and security access control requirements of the collaborative design of information security solutions.This thesis presented a system security framework for network-based collaborative design data information management: using dynamic mechanism for the realization of dynamic random password authentication protected the identity of the user's security; based on RSA public key encryption system digital signature ensured the safety of workflow, Non-repudiation and the integrity of the document; based on SSL security protocol ensured data security, integrity and authentication of networked collaborative design; using an access control methods of XACML-based control strategy, through the XACML strategy documentin order to meet the needs of the access control, achieved a unified focus on access control, increased the flexibility of the control system resources. We achieved the above-mentioned program on WEB-based networkingcollaborative design data management and security protection, and introduced detailedly authentication module, digital signature module, SSL transmission components, as well as XACML-based access control modules designed to achieve specific process.Through the initial development and testing, the various security module of design meeted basically the designed requirements.
