As a part of its work, the working group will define the new IPv6-based routing header in way that blind attacks are never possible, i.e., attackers will be unable to send source routed packets that get successfully processed, without being part of the negations for setting up the source routes or being able to eavesdrop legitimate source routed packets. In some networks this base level security may be complemented with other mechanisms, such as packet filtering, cryptographic security, etc.

that would work for me. 

Thanks.

It would also help deployment, as firewalls might otherwise default to blocking all kinds of routing headers.
