In mathematics, a proof is the demonstration of an absolute truth, but in #crypto, a proof is only the demonstration of a relative truth.
One issue is with the phrase “proof of security” itself. In mathematics, a proof is the demonstration of an absolute truth, but in crypto, a proof is only the demonstration of a relative truth. For example, a proof that your cipher is as hard to break as it is to compute discrete logarithms—finding the number x given g and gx mod n—guarantees that if your cipher fails, a whole lot of other ciphers will fail as well, and nobody will blame you if the worst happens. #cryptography #cryptographicsecurity #security #africa #cybersecurity #socialmedia
