Current work on authentication

Andrew Birrell, Butler W. Lampson, Roger Needham, and Michael D. Schroeder


We have been working on a design for an authentication service for a distributed system. The design has three goals that we fed have not been met simultaneously by any previous design. First, the service must be able to grow to cover an arbitrarily large physical area, arbitrarily many administrative organizations, and arbitrarily many users (milliom or billions); the service must be suitable for a long lifetime. Second, the system must not be monolithically trusted: it must be possible to achieve authentication even if there exist untrusted parts of the system. Third, these goals must be met in such a way that each party to the authentication knows precisely what agencies the party must trust in order to accept the authentication.
