| Abstract: | The Grid is widely seen as the next generation Internet. Aims to
share dynamic collections of individuals, institutions and
resources by providing consistent, easy and inexpensive access
to high-end computational capabilities. Studies Grid security and
specifically users’ access control. It has been proved that the
viability of these heterogeneous environments is highly
dependent on their security design. Solutions trying to address
all aspects of security were proposed by most existing Grid
projects and collaborations; however the results were not always
satisfactory. Reviews some of the most widely-accepted security
solutions, and collects the most efficient. Emphasizes access
control procedures and the solutions addressing authentication
and authorization issues. Identifies the most successful security
schemes implemented and illustrates their effectiveness. Collects
these mechanisms to form the backbone of a security
mechanism, addressing authentication and authorization Gridspecific
problems. The proposed schemes can constitute the
backbone of an effective Grid security architecture. |
