OSPFv3 uses one-hop IPSec AH for authentication. You can also use ESP for payload encryption.

Key word: OSPF V3
OSPFv2 authentication is achieved by implementing a shared secret and MD5 HMAC supported as part of the OSPFv2 protocol. OSPFv3 does away its own support for authentication entirely, instead relying on the more flexible IPsec framework offered by IPv6.
