PFSC: A research on public file scan and certificate in grid

Security is one of the most important issues in grid computing. Therefore it is an inevitable function in most kinds of grid middleware to ensure the security of resource access. Efforts of this literature focus on file security in grid system. An architecture for file scan and monitoring is proposed on top of OGSA-based grid middleware as well as NFS, for the purpose of preventing the spread of virus via the file transfer and sharing over grid.
