Chapter Ii Literature Survey on Grid Security Models and Mechanisms

The previous chapter of this thesis describes various aspects of grid computing environment and the security issues associated with grids. In this chapter, we present a detailed survey of relevant literature in grid computing security. The aim of this survey work is to present current research trends from the point of view of the security models and authorization mechanisms available in the grid computing environment. Efforts have been made to present an up-to-date research information with details of approaches, algorithms and implementation systems that have been developed and used during the last decade of grid computing evolution. The chapter has been organized as follows. First we review the literature work in the general area of grid computing security. In section 3, we present various schemes in the grid access control. Section 4 discusses the grid authorization attempts. Section 5 presents the research in trust relationships in grid computing. Next, we present the security issues identified as part of this survey. Section 7 discusses the need for grid access control and the characteristics of an ideal grid security mechanism. Finally we summarize the chapter.
