Abstract

Security and safety problems are two of the main factors that hinder the development and practicality of distributed system. They are not only very important, but also closely related. But at present most of the researches only focuses on the aspect of security. However, with the massive use of software and the change of fault models, the distributed system is facing a severe challenge in its safety policy and needs some new type of safety protection mechanism. Based on thorough analysis of the security and safety needs of distributed system, it is proposed in this paper a new type of security and safety assurance structure that integrates both elements of security and safety. Discussions are laid on the characteristics of the new structure and the aim of its design. In view of the difficulty in applying the new structure to the large-scale distributed system, this paper proposed a solution that is based on real- time operating system. Finally, a new structure SADS (security and safety architecture of distributed system) is constructed and its feasibility and effectiveness are also proved by building SADS with traffic lights system on RT-Linux platform.
