发明名称 Internet/bank card electronic signature generation having quadratic equation generation and signature calculated using hash public function with supplementary private values preventing hacking.
摘要 The public key generation method has quadratic equations with unknowns belonging to a finite body. A signature is calculated from a message verifying M equals to y1 to ym equals Hash(M) where M is a public function. The Hash public function is chosen from random variables and supplementary secret values. Only the public key is known not the secret key, and thus hacking is not possible. The public key electronic signature method has a verification step verifying the message and its signature, using a Hash function chosen from random variables and supplementary secret values. The public key is known by the recipient not the secret key, thus preventing hacking.
