Yes, but doesn't the CAI system work? It is my impression that it is
perfectly secure and has never been compromised. So why suddenly call it
"insecure".

What is the plan to get the approval back in place? What must CAI do to
make it meet your new requirements?

Public key cryptography was well known in 1994 when the Cambridge 10's
were used at the NZ pre-worlds, and in fact I *told* them at the time
that they should be using something like RSA instead of something
home-grown.

Oh well.
