Abstract: In broker architecture in the grid, providing a secured service is still a great challenge. Further, the trust values of the service provider need to be shared confidentially. As a grid contains a wide variety of services, the level of security too needs to be flexible with the type of service. Hence, in this study, the authors propose an adaptive security mechanism for such broker architecture. This multi-level security mechanism is mainly to ensure that a highly sensitive transaction be treated severely with security so that its confidentiality and the value of the data, being transmitted doesn`t get lost. This is achieved with the shared key agreement with tickets for authentication and using a rotating key mechanism from there on.
