In grid computing, heterogeneous computing stations spread out in the world can connect to the grid and offer services or request services in a loosely coupled environment withservices-on-demandstyle. Public key infrastructure (PKI) is the most widely adopted security infrastructure used in grid environments. We have developed a scheme for dynamic token generation in a grid environment ensuring more security and less hack proneness because of the dynamic changing of the token which is used in all transactions. The dynamic token thus generated forms part of the private key and the user id of the client provides the public key in terms of PKI. The dynamic token helps in establishing proof of origin to the receiver and also mutual trust (client verifies the identity of the server and server verifies identity of the client).
