Improved Arcfour Modes for the Secure Shell (SSH) Transport Layer Protocol
Draft of message to be sent after approval:
From: The IESG <email@example.com> To: IETF-Announce <firstname.lastname@example.org> Cc: Internet Architecture Board <email@example.com>, RFC Editor <firstname.lastname@example.org> Subject: Protocol Action: 'Improved Arcfour Modes for the Secure Shell (SSH) Transport Layer Protocol' to Proposed Standard The IESG has approved the following document: - 'Improved Arcfour Modes for the Secure Shell (SSH) Transport Layer Protocol ' <draft-harris-ssh-arcfour-fixes-04.txt> as a Proposed Standard This document has been reviewed in the IETF but is not the product of an IETF Working Group. The IESG contact person is Sam Hartman. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-harris-ssh-arcfour-fixes-04.txt
Technical Summary This document specifies methods of using the Arcfour cipher in the Secure Shell (SSH) protocol which mitigate the weakness of the cipher's key-scheduling algorithm. Working Group Summary This document is not the product of any working group but has been reviewed on the secsh working group list. IETF last call discussed whether it was appropriate to recommend RC4 for use in standards track protocols. As a result of these comments an applicability statement was added, recommending draft-ietf-secsh-newmodes to this specification in many situations. Since there is an existing standards-track RC4 cipher and since this cipher is clearly more secure than that existing cipher specification this document is being published on the standards track. Protocol Quality This document has been reviewed for the IESG by Sam Hartman.
