Re: [Smart] [Secdispatch] New Version Notification for draft-lazanski-smart-users-internet-00.txt

It is an interesting read. But I see a very important distinction that
needs to be made between compromise of user end points and compromise of
server end points.

Most breaches that occur are when an enterprise is penetrated and the
firewall is the first and last line of defense. So Percy the Pinhead clicks
on a link in an email and six hours later the attacker has root privilege
on the corporate server. This is not Percy's fault, the fault is that a
single mistake by a single employee results in compromise of data Percy was
never authorized to access.

So right now we have systems where one compromise at any one of 10,000
endpoints results in a breach.

Now lets consider using some 1980s style end to end cryptography. So that
the ultra important recipe data is only available to the dozen members of
group. This improves matters because we have reduced the points of
compromise from 10,000 cooks and service staff to 12 trusted employees.

That is a start but we are still vulnerable to a single end point
compromise so lets apply threshold cryptography so members of group W only
have one half of the decryption key, the other is on the server and both
halves of the key are needed to perform decryption. In this scenario, we
now require two separate compromises of two different end points.
