Abstract
A distributed authentication model that operates within a protocol-based sphere of trust. Rather than being able to communicate with any one of the computing systems internal to the sphere of trust, the amount of authentication is reduced by having the external computing systems initially communicate with a specific edge internal computing system. Many if not all of the internal computing systems then delegate the task of authentication to the edge computing system, and will rely on any authentication performed by the edge computing system. This allows the task of authentication to scale well for large protocol-based spheres of trust.
