Abstract(in English) Diffie-Hellman key exchange and the key exchange method with public key cryptosystem has been typical key exchange method. These standerd methods were vulnerable to Man-in-the-middle Attacks. Then, new methods improved sacurity against Man-in-the-middle Attacks by combining authentication with PKI is studied, and used generically now. however, two problems occur when those methods use the authentication by PKI. one is the cost which to issue and to manage public key certificate, and another is a problem that is necessary to be able to connect to certificate authority to verify public key certificate. In this paper, we propose the method that combine key exchange and direct input by user especially for PDA. Direct input function in authentication in place of PKI. As a result, we examined the effectiveness of the proposed method by the comparison with existing methods, and mentioned application examples.
