                HTTP Origin-Bound Authentication (HOBA)
                      draft-ietf-httpauth-hoba-00

Abstract

   HTTP Origin-Bound Authentication (HOBA) is a design for an HTTP
   authentication method with credentials that are not vulnerable to
   phishing attacks, and that does not require a server-side password
   database.  The design can also be used in Javascript-based
   authentication embedded in HTML.  HOBA is an alternative to HTTP
   authentication schemes that require passwords with all the negative
   attributes that come with password-based systems.  HOBA can be
   integrated with account management and other applications running
   over HTTP and supports portability, so a user can associate more than
   one device or origin-bound key with the same service.  We also
   describe a way in which the HOBA design can be used from a Javascript
   web client.  When deployed, HOBA will be a drop-in replacement for
   password-based HTTP authentication or JavaScript authentication.
