The following errata report has been submitted for RFC6506, "Supporting Authentication Trailer for OSPFv3". -------------------------------------- You may review the report below and at: http://www.rfc-editor.org/errata_search.php?rfc=6506&eid=3335 -------------------------------------- Type: Technical Reported by: Manav Bhatia <manav.bhatia@alcatel-lucent.com> Section: 4.5 Original Text ------------- If the Protocol-Specific Authentication Key (Ks) is L octets long, then Ko is equal to K. Corrected Text -------------- If the Protocol-Specific Authentication Key (Ks) is L octets long, then Ko is equal to Ks. Notes ----- The key K is never used in computing the digest. There is a class of cross protocol attacks that can be prevented if the original key K is appended with a few well known bytes. As a result, the key K is appended with a 2 octet crypto protocol ID to derive a new key Ks. Its this key that must always be used. Instructions: ------------- This errata is currently posted as "Reported". If necessary, please use "Reply All" to discuss whether it should be verified or rejected. When a decision is reached, the verifying party (IESG) can log in to change the status and edit the report, if necessary. -------------------------------------- RFC6506 (draft-ietf-ospf-auth-trailer-ospfv3-11) -------------------------------------- Title : Supporting Authentication Trailer for OSPFv3 Publication Date : February 2012 Author(s) : M.
