Often an information source on the Web would like to provide different classes of service to different clients. In the autonomous, highly distributed world of the Web, the traditional approach of using authentication to differentiate between classes of clients is no longer sufficient, as knowledge of a client's identity will often not suffice to determine whether a client is authorized to use a service. In (Ching et al., 1996) we proposed the use of digital credentials to help solve this problem; but their use will in turn introduce a bevy of new problems associated with credential management. In this paper we propose the use of server security policies and client credential submission policies to aid in the management of a client's digital credentials. We propose a structure for such policies, and briefly describe an implementation of personal security assistants and server security assistants that embodies our proposed approach
