The IESG has received a request from the Domain Name System Operations WG (dnsop) to consider the following document: - 'Interoperable Domain Name System (DNS) Server Cookies' <draft-ietf-dnsop-server-cookies-04.txt> as Proposed Standard
The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the [email protected] mailing lists by 2020-12-04. Exceptionally, comments may be sent to [email protected] instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract DNS Cookies, as specified in [RFC7873], are a lightweight DNS transaction security mechanism that provide limited protection to DNS servers and clients against a variety of denial-of-service and amplification, forgery, or cache poisoning attacks by off-path attackers. This document provides precise directions for creating Server Cookies so that an anycast server set including diverse implementations will interoperate with standard clients. This document updates [RFC7873] with * suggestions for constructing Client Cookies in a privacy preserving fashion, * precise instructions for constructing Server Cookies deprecating the methods described in [RFC7873], and * suggestions on how to update a server secret. An IANA registry listing the methods and associated pseudo random function suitable for creating DNS Server cookies is created, with the method described in this document as the first and as of yet only entry. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-dnsop-server-cookies/ No IPR declarations have been submitted directly on this I-D. _______________________________________________ DNSOP mailing list [email protected] https://www.ietf.org/mailman/listinfo/dnsop
