ABSTRACT:
A method for exchanging an authentication and signing an electronic signature, capable of providing a high security and achieving a high efficiency. The method includes the steps of setting p, q and g as system parameters, where p and q are prime numbers while g is an integer, between 1 and p, having the value of 1 when multiplied by the q-th power and then divided by p, and using n secret keys and n public keys for each user, where n is a number not less than 2, the public keys v.sub.n respectively corresponding to the secret keys S.sub.n, integers between 1 and q, and being produced based on an equation of v.sub.n =g.sup.-sn mod p.
