Web7. We don't prove schemes like AES and DES secure. Instead, cryptanalysts try very hard to find attacks against the scheme. If, after much effort, no attack is found, we may with some justification consider the scheme secure. The statement that a scheme is secure usually takes the form "any adversary that breaks the scheme with this much ...
