[ipv6hackers] IPv6 security presentation at Hack.lu 2011

[Jim Small]

The problem with SeND is limited O/S implementations.  I know there is Linux support, but Windows doesn't support it and I don't believe OS X does either.  There are many ideas for IPv6 security, mobility (MIPv6), and multi-homing (SHIM6) - but without mainstream native O/S support they seem to be limited to a lab.  My impression is that Microsoft and Apple have essentially no interest in these areas.

Hi Fernando,

At first thanks for the slides! Great job summarizing the state of the
art about IPv6 security!

Now, I have comments:
-  Address resolution
"SEND is very difficult to deploy (it requires a PKI)"
AFAIK, you don't need a PKI. CGA is enough to secure NS/NA exchanges.
Now, the main issue, IMHO, is hard-coded crypto algorithms: SHA-1,
that should be replaced by the future SHA-3, and RSA, which is not
very well adapted to constrained devices like sensors.
- Auto-configuration
"SEND is very difficult to deploy (it requires a PKI)"
s/PKI/RPKI (cf. draft-ietf-csi-send-cert)
And again, AFAIK, RIRs are currently working to deploy RPKI (e.g.,
http://www.rpki.net for ARIN) and openssl already allows to generate
the needed certificates. Now I agree there is still work to deploy
this technology in product networks.
- IPsec Support
"The IETF has acknowledged this fact, and is currently changing IPsec
support in IPv6 to "optional""
Sorry, but IPsec support is still a "SHOULD" (v.s. "MAY" meaning
optional) and so IPsec is not optional unless specific constraints
(like sensors).
Now, as raised many times, the main issue with IPsec is Key Management
(e.g., pre-shared key, certs, EAP).

Best regards.

JMC.
