Electronic signature generating method, e.g. for use in chip card, involves generating random number from set of integer modulo and calculating and storing predetermined values based on hashing functions
摘要
<p>Electronic signature generating method involves generating a random number from a set of integer modulo, and calculating and storing predetermined values using the hashing functions. An electronic signature of a message is produced based on the calculated predetermined values. Independent claims are also included for: (A) A method for verifying electronic signature; (B) An electronic signature scheme; and (C) A portable electronic component including a unit for implementing a method for generating and verifying an electronic signature.</p>
