| Abstract(in English) | We consider the unforgeability of the cryptographic protocols using the signatures. A signature is said to be forgeable if a user can get more signatures thatn the signer gives him. In this paper, for a given cryptographic protocol using signatures, the decision problem to decide whether or not all signatures can be issued are unforgeable is discussed. In signature schemes, the one-way hash functions are often used to compress a signing message. Taking account of the usage of one-way hash functions in the protocol, we present a sufficient condition under which the problem is decidable. |
