In a system based on distributed services,the upper-level application system requests the lower-level security services to provide various security functions according to the former’s demands, to adjust the service relationship with different service providers on different requests automatically along with the change of the current requests and states, to protect the security at the same time. A negotiation protocol model based on the quality of protection which is used between applications and security services is presented here,and its goal is to ensure the security services' support and abidance on the security standard required by the applications, which will ensure the general security of the whole system.
