 The experiments demonstrating loophole-free violations of Bell inequalities take on particular significance in this context. The toy models demonstrating the reality of the detector inefficiency loophole lack physical plausibility, and, in the absence of conspiracies aimed at deceiving the experimenters, may be disregarded on the assumption that nature, though subtle, is not malicious. Cryptography, on the other hand, by its very nature must take into account the possibility of a conspiracy aimed at deceiving the users of a cryptographic key, and so, in this context, it is essential to demonstrate security in the presence of such a conspiracy.
