No, not with words, as we're all so fond of doing. Instead, I suggest that the NSA or others provide free access to an EES system on the 'net, for any and all to attempt attacks. They could hook up a workstation or two with a couple Tessera cards, and provide anonymous login access. All functions should be permitted as they will be in a final implementation. This is an inexpensive way that EES advocates can permit access to the system for analysis. It would be only for research purposes--there'd be no way to encrypt a phone conversation, and anybody would have to be stupid to encrypt sensitive data with an NSA-owned machine, even assuming you could get the data to the computer securely in the first place. To the NSA agent who is surely subscribed: if Clipper is so great, prove it. If you won't disclose the Skipjack algorithm (but why not if it's secure?), at least provide access to test its implementation. b& -- Ben.Goren@asu.edu, Arizona State University School of Music net.proselytizing (write for info): Protect your privacy; oppose Clipper.
