A New Internet-Draft is available from the on-line Internet-Drafts directories. Title : Hypertext Transfer Protocol (HTTP) Digest Authentication Using Authentication and Key Agreement (AKA) Version-2 Author(s) : V. Torvinen, J. Arkko Filename : draft-torvinen-http-digest-aka-v2-00.txt Pages : 16 Date : 2003-6-16 HTTP Digest is known to be vulnerable to man-in-the-middle attacks, even when run inside TLS, if the same passwords are used for authentication in some other context without TLS. This is a general problem that affects not just HTTP digest but also other IETF protocols. However, for a class of strong algorithms the attack is avoidable. This document defines version 2 of the HTTP Digest AKA algorithm. Unlike previous versions of HTTP Digest such as MD5 or AKAv1, this algorithm is immune to the man-in-the-middle attack. A URL for this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-torvinen-http-digest-aka-v2-00.txt To remove yourself from the IETF Announcement list, send a message to ietf-announce-request with the word unsubscribe in the body of the message. Internet-Drafts are also available by anonymous FTP. Login with the username "anonymous" and a password of your e-mail address. After logging in, type "cd internet-drafts" and then "get draft-torvinen-http-digest-aka-v2-00.txt". A list of Internet-Drafts directories can be found in http://www.ietf.org/shadow.html or ftp://ftp.ietf.org/ietf/1shadow-sites.txt Internet-Drafts can also be obtained by e-mail. Send a message to: mailserv@ietf.org. In the body type: "FILE /internet-drafts/draft-torvinen-http-digest-aka-v2-00.txt". NOTE: The mail server at ietf.org can return the document in MIME-encoded form by using the "mpack" utility. To use this feature, insert the command "ENCODING mime" before the "FILE" command. To decode the response(s), you will need "munpack" or a MIME-compliant mail reader. Different MIME-compliant mail readers exhibit different behavior, especially when dealing with "multipart" MIME messages (i.e. documents which have been split up into multiple messages), so check your local documentation on how to manipulate these messages. Below is the data which will enable a MIME compliant mail reader implementation to automatically retrieve the ASCII version of the Internet-Draft.
