摘要	The semantic grid (SG) aims at connecting information silos of web into a gigantic database, and supplying only the useful information to the users. Much advance has been made on information representation, extraction and sharing, but access control in SG is seldom discussed. This paper presents an access control model for semantic gird, which uses asynchronous automata to simulate grid nodes and grids. The classic Bell-LaPadula model is extended to deal with security properties of SG. Based on application scenarios of information sharing in China railways industry, this model is used to study convergence and consistence problems in SG. A prototype is implemented to verify our model. (C) 2003 Published by Elsevier B.V.
