Re: Attacking Clipper with timing info?

Without having the details of the algorithm, I suspect the answer is 'remotely possible, at best'.

However, to extend what I suspect you were getting at:

It would be very interesting to determine if the NSA knew about this crypto-design problem...

That was indeed what I was wondering. I expect we wont have to wait too long before we hear whether Clipper chips require the same or a different amount of time to encrypt/decrypt. Should be interesting. Jim_Miller@suite.com
