Abstract

Within the Architecture for describing Simple Network Management Protocol (SNMP) Management Frameworks [RFC3411], the User-based Security Model (USM) [RFC3414] for SNMPv3 is defined as a Security Subsystem within an SNMP engine. In RFC 3414, two different authentication protocols, HMAC-MD5-96 and HMAC-SHA-96, are defined based on the hash functions MD5 and SHA-1, respectively.

                  HMAC-SHA-2 Authentication Protocols in                User-Based Security Model (USM) for SNMPv3

Abstract

   This document specifies several authentication protocols based on the    SHA-2 hash functions for the User-based Security Model (USM) for    SNMPv3 defined in RFC 3414.  It obsoletes RFC 7630, in which the MIB    MODULE-IDENTITY value was incorrectly specified.
