This Working Group did not meet
NOTE: This charter is a snapshot of the 54th IETF Meeting in Yokohama, Japan. It may now be out-of-date.
Last Modifield: 07/31/2001
The object of this working group is to write a standards track RFC for one-time password technology, using the technology in the Bellcore S/KEY system and related interoperable packages (e.g., logdaemon, NRL OPIE) as the basis for the group's effort. The standards-track RFC will enhance multi-vendor interoperability in one-time password authentication technologies and thereby help reduce security risks in the Internet.
General authentication servers are outside the scope of this working group. The ``S/Key-0'' system being considered for use in Kerberos is outside the scope of this working group.
The standards-track specification will describe how this one-time password technology can be used with at least the MD4, MD5, and SHA algorithms. The standard one-time password dictionary from RFC 1760 will be reused in order to maintain backwards compatibility with the various deployed systems, however, support for hexadecimal format passwords will also be mandatory to implement. The standard might specify passphrase quality checks for the secret passphrase. The standard will be specified so as to eliminate any possible conflict with the Bellcore trademark on the term ``S/Key.''
An Informational RFC might also be issued that describes conventions for the UNIX commands relating to one-time passwords, including command(s) to securely update a remote one-time password.
