Often in practice, however, a user authenticates using some credential chain: a root organization gives a credential to an intermediate party who can in turn use this to issue credentials to user.<br \/>\nWe address this problem by presenting the first efficient delegatable anonymous credential scheme. In such a scheme, a party can receive credentials from an organization, and then anonymously and unlinkably issue delegated credentials to other users, who can in turn delegate these credentials to another level. Then a user can prove possession of a valid chain of credentials of a given length without revealing any other identifying information. This talk will describe our result and outline some of the main techniques used to achieve it.<\/p>\n<\/div>\n<p><!-- .asset-content --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Anonymous credential systems allow users to anonymously obtain credentials from organizations, and to anonymously and unlinkably prove possesion of valid credentials.
