| Abstract(in English) | We discuss the decision problem of cryptographic protocols which decide whether the reply for a message is forgeable or not in a given cryptographic protocol. A simple sufficient condition was shown under which the problem is decidable. In this paper, we show a new sufficient condition which relaxes the subcondition about the operations which opponents can execute. A polynomial-time algorithm is also shown for the problem which satisfies the condition. |
