A security architecture for computational grids
Ian T Foster, Carl Kesselman, Gene Tsudik, Steven Tuecke · 1998
State-of-the-artand emerging scientific applications require fast access to large quantities of data and commensurately fast computational resources.Both resources and data are oflen distributed in a wide-area network with components administered locally and independently.Computations may involve hundreds of processes that must be able to acquire resources dynamically and communicate efficiently.This paper analyzes the unique security requirements of large-scale distributed (grid) computing and develops a security policy and a corresponding security architecture.An implementation of the architecture within the Globus metacomputing toolkit is discussed.
