Abstract

In this paper we propose a fine-grained workflow model, based on context-free graph grammars, in which the dependency relation between the inputs and outputs of a module is explicitly specified as a bipartite graph. Using this model, we develop an access control mechanism that supports provenance-aware security views. Our security model not only protects sensitive data and modules from unauthorized access, but also provides the flexibility to expose correct or partially correct data dependency relationships within the provenance information.
