Patent number: 9959493Abstract: Methods for authenticating printer supply items using revocation lists are disclosed. Revocation lists are updated using DNSSEC to communicate between a printer and a DNS name server. A first domain name is created containing a request for a challenge to an authentication module and sent to the DNS name server. A second domain name is created containing a response to the challenge and sent to the DNS name server. The DNS name server indicates success or failure, which is used to authenticate the printer supply item. Other systems and methods are disclosed.Type: GrantFiled: March 8, 2016Date of Patent: May 1, 2018Assignee: Lexmark international Inc.Inventors: Christopher Alan Adkins, James Ronald Booth, Matthew David Clarke, Graydon Randall Dodson, Joshua Scott Potter
