Abstract: Many
research efforts are being undertaken to improve shared resources security
between Virtual Organizations (VO) in a grid environment, but user security is
threatened as organizations in VO keep changing dynamically. VO access should
be established only through trust relationships between VO and local users.
Generally, there is no trust relationship between classical organization and VO
or external members. Access to VO resources by organizations users is only when
they possess a Certifying Authority (CA) provided certificate. Additional
computing overheads increasing computational overheads are a disadvantage of
using public-key for authentication. This paper proposes a novel authentication
mechanism through the use of a public key concept being generated from the
local Community Authorization Service (CAS) and not CA for increased speed. The
proposed architecture accesses resources with dynamically generated keys and a
token instead of signing in with credentials for every access by users.
Simulation results prove that VO performance improves with the proposed
mechanism.
