As we know that security is an important issue in distributed system, that create many problems when a user want to access, or accessing services through the internet then credential management acting a main role in enhancing the security of that system, or an organization. In this proposed work w provide security solution with the help of Open PGP (RFC 4880) certificates in Grid Framework. Open PGP is nothing but it is an email encryption standard. In explanation I want to say that X.509 certificates are issuing by certification authority (CA) that certified by multiple companies, it secure by own point of view but when it is used distributed Grid system infrastructure then it becomes quite unsecure, when updating alert send to admin of the database through email then some email attacks may be possible like man in middle attack, pretexting, phishing etc.

Grid computing X.509, PGP, Pretexting, Man In Middle attack.
