HMAC-SHA-2 Authentication Protocols in the User-based Security Model (USM) for SNMPv3
Draft of message to be sent after approval:
From: The IESG <email@example.com> To: IETF-Announce <firstname.lastname@example.org> Cc: RFC Editor <email@example.com> Subject: Protocol Action: 'HMAC-SHA-2 Authentication Protocols in USM for SNMPv3' to Proposed Standard (draft-ietf-opsawg-hmac-sha-2-usm-snmp-06.txt) The IESG has approved the following document: - 'HMAC-SHA-2 Authentication Protocols in USM for SNMPv3' (draft-ietf-opsawg-hmac-sha-2-usm-snmp-06.txt) as Proposed Standard This document is the product of the Operations and Management Area Working Group. The IESG contact persons are Benoit Claise and Joel Jaeggli. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-opsawg-hmac-sha-2-usm-snmp/
Technical Summary This memo specifies new HMAC-SHA-2 authentication protocols for USM using an HMAC based on the SHA-2 family of hash functions. They are straightforward adaptations of the authentication protocols HMAC-MD5-96 and HMAC-SHA-96 to the SHA-2 based HMAC. Working Group Summary During the adoption call we discovered that there was another document (https://datatracker.ietf.org/doc/draft-hartman-snmp-sha2/) which did something very similar. This document had been written earlier, but neither the document authors, nor most of the OpsAWG WG was aware of it. The CfA stalled for a long time while we asked the WG to decide which option they proffered, and to see if there was a clean way to combine the two documents. In the end, the authors of hartman-snmp-sha2 agreed that this document (hmac-sha-2-usm-snmp) should progress. Document Quality The document is well written and clear. David Reid (at least) has implemented this ("We have also implemented it (using private OIDs for now).") Personnel Warren Kumari will be the document shepherd. Joel Jaeggli is the AD.
