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.<\/p>\n<\/div>\n<p><!-- .asset-content --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>We have been working on a design for an authentication service for a distributed system.
