OSPF WG has come out with a mechanism that can be used to secure
OSPFv3 without IPsec -
http://tools.ietf.org/html/draft-ietf-ospf-auth-trailer-ospfv3-11

It should get published as an RFC any time now.

BTW, there isnt any standard for using IPsec with OSPFv2, so youre
probably using a proprietary solution. I think a better solution is to
move to OSPFv3-AT, as its very similar to OSPFv2 authentication.
