RFC 3310 Title: Hypertext Transfer Protocol (HTTP) Digest Authentication Using Authentication and Key Agreement (AKA) Author(s): A. Niemi, J. Arkko, V. Torvinen Status: Informational Date: September 2002 Mailbox: firstname.lastname@example.org, email@example.com, firstname.lastname@example.org Pages: 18 Characters: 36985 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-sip-digest-aka-03.txt URL: ftp://ftp.rfc-editor.org/in-notes/rfc3310.txt This memo specifies an Authentication and Key Agreement (AKA) based one-time password generation mechanism for Hypertext Transfer Protocol (HTTP) Digest access authentication. The HTTP Authentication Framework includes two authentication schemes: Basic and Digest. Both schemes employ a shared secret based mechanism for access authentication. The AKA mechanism performs user authentication and session key distribution in Universal Mobile Telecommunications System (UMTS) networks. AKA is a challenge-response based mechanism that uses symmetric cryptography. This document is a product of the Session Initiation Protocol Working Group of the IETF.
