A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Internet Architecture Board Working Group of the IETF. Title : A Survey of Authentication Mechanisms Author(s) : E. Rescorla Filename : draft-iab-auth-mech-00.txt Pages : 33 Date : 2003-4-28 Authentication is perhaps the most basic security problem for design- ers of network protocols. Even the early Internet protocols such as TELNET and FTP, which provided no other security services, made pro- vision for user authentication. Unfortunately, these early authenti- cation systems were wholly inadequate for the Internet Threat Model [REF] and a vast array of other authentication mechanisms have been introduced in an attempt to close these holes. The most striking thing about these security mechanisms is how many of them are essentially similar. There are only 7 basic classes of authentication protocol but there are a large number of slightly dif- ferent protocols with essentially the same security properties. This memo surveys the space of authentication mechanisms, describes the basic classes and provides examples of protocols which fit into each class.

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-iab-auth-mech-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-iab-auth-mech-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.
