If you (or a small team) are good enough to write crypto code that has =
no side channels, no timing issues across the branches (or power surges =
twiddling coils in what seems to a fashionable manner) - then you darn =
well should be able to squeeze in a little channel of your own. Defence =

destruction.

I doubt that this is a technical issue; it is a social and geopolitical =
one. Having some french, german and russian folks agree with their =
American and Chinese brethren on something is a good start.
