Background “Scalar multiplication” is a fancy way of saying multiplication by repeated additions. Elliptic curves only have a point addition operation, so to multiply a point by 5 we do ... WebCryptography, the use of codes and ciphers to protect secrets, began thousands of years ago. Until recent decades, it has been the story of what might be called classical cryptography — that is, of methods of encryption that use pen and paper, or perhaps simple mechanical aids.
