The computational Grid concept allows resource sharing in large scale. This work
introduces the ProGrid system, an architecture for computational Grids, whose
communication and resource management infrastructure is used transparently by the
applications. Unlike other grid approaches, this work relies on the use of proxy servers to
perform additional communications and authentication procedures on behalf of client
applications. The purpose of this mechanism is to enable parallel applications to be
executed in geographically distributed environments interlinked by an open
communication network, such as the Internet, meeting the security requisites desirable for
computational grids. To reach such objectives, a generic architecture for ProGrid was
developed, that is divided in a group services layers. This work was focused in the
implementation of layers responsible by the secure communication and for the controlled
sharing of available resources.
