Another significant Shamir contribution is differential cryptanalysis, which is rapidly becoming a fundamental tool in the design of new secret key ciphers. However, the present state of affairs is claimed to be that the open discussion and publication of cryptographic algorithms is not export controlled -- only actual implementations are. Therefore you're missing the mark by talking about whether non-Americans make significant contributions to the theory of cryptography. Even if only Americans made them they'd still be available worldwide. You ought instead to ask the question whether there are any non-Americans capable of turning an algorithm description into working code. Evidently the US State Department doesn't think so and nor do you, since you defend this interpretation so strongly. Phil
