A New Internet-Draft is available from the on-line Internet-Drafts directories. Title : Secure IPv6 Address Proxying using Multi-Key Cryptographically Generated Addresses (MCGAs) Author(s) : J. Kempf, C. Gentry Filename : draft-kempf-mobopts-ringsig-ndproxy-02.txt Pages : 17 Date : 2005-8-23 RFC 3971 and 3972 (SEND) define a protocol for securing resolution of a statelessly autoconfigured IPv6 address to a link address as defined by IPv6 Neighbor Discovery. SEND does this by requiring the autoconfigured addresses to be cryptographically generated by the host from an RSA public key. However, one drawback of SEND is that such addresses cannot be securely proxied. Proxy Neighbor Discovery is important for Mobile IPv6 and in certain other cases. In this document, we describe an extension of SEND to addresses that are cryptographically generated using multiple public keys, called multi- key CGAs. Neighbor Discovery messages for multi-key CGAs are signed with an RSA ring signature, a type of signature that can be generated using the private key of any node from a group of nodes but which requires the public keys of all group members to verify. Multi-key CGAs can be securely proxied by all nodes that contribute keys to the address. The advantage of multi-key CGAs over other techniques of secure address proxying, such as trusting the router or using an attribute certificate, is that it preserves location privacy. A receiver cannot determine from the IPv6 address, ring signature, or cryptographic parameters whether the node or the proxy is defending the address, and hence whether the node is on or off the link.

You can also visit https://www1.ietf.org/mailman/listinfo/I-D-announce to change your subscription settings. 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-kempf-mobopts-ringsig-ndproxy-02.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-kempf-mobopts-ringsig-ndproxy-02.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.
