New Release Announcement

We are pleased to announce the availability of a new reference implementation of GAA-API (Generic Authorization and Access control Application Programming Interface, GAA-API v0.7). This code is provided as an academic contribution for joint exchange. It is experimental and is provided ``as is''.

Applications invoke GAA-API functions to check authorization against an authorization model. The API functions obtain policies from local files, distributed authorization servers, and from credentials provided by the user. The functions combine local and distributed authorization information under a single API based on the requirements of the application and applicable policies, and request credentials if necessary.

A module is provided to support a simple policy language called, Extended Access Control Lists (EACL) that is designed to describe user-level authorization policy. The GAA-API provides a general-purpose execution environment in which EACLs are evaluated. EACL is one of the possible policy languages supported by the GAA-API. The underlying architecture of the GAA-API allows different policy languages to co-exist in one execution environment.
