Kerberos authentication and authorization system

This document describes the assumptions, short and long term goals, and system model for a network authentication system, named Kerberos, for the Athena environment. An appendix specifies the detailed design and protocols to support these goals, and a set of 1 UNIX manual pages, not included here, describes an implementation for Berkeley 4.3 UNIX of both user interface commands and also library interfaces for clients and servers. The next section of the technical plan, E.2.2, describes a set of network applications that use Kerberos for authentication.
