IPv4 Headers Investigated

An anonymous reader writes "New security measures are being suggested (see RFC 3514) for the IPv4 header. The measures include a bit that can be set and unset according to whether the packet is secure or not. Due to the important security implications, anyone coding client/server internet applications might want to take a look."

This is a recording. At the tone we'll post another story on RFC-3514.

Then again....
