Abstract: PROBLEM TO BE SOLVED: To provide a secure password-only mutual network authentication protocol which is provably secure. SOLUTION: Between two parties A and B sharing a password through a data network, a shared secret key g<xy> is generated by using Diffie-Hellman type key exchange concerning a specified group. In such a case, (g) is a group generator known by both the parties, (x) is an index known to one party (client, for example) A and (y) is an index known to the other party (server, for example) B. The party A generates a parameter (m) by applying group operation to g<x> and a function H1 of the password at least and transmits (m) to the party B. In the result of the function H1 , the part outside the group is made random. Thus, the person B applies inverse group operation to be (m) and the function H1 , extracts g<x> by removing the randomization of any portion outside the group in the result of the function H1 and further can calculate the shared secret g<xy> .
