PROBLEM TO BE SOLVED: To provide a method for setting a parameter for cryptocommunication which is intuitive, intelligible and highly reliable. SOLUTION: This method for setting a parameter uses a device having a communication means provided with a terminal for performing connection by physical contact and a means for recording parameters such as identification information obtained by collecting the following data: cryptographic algorithm, authentication algorithm, a key and the identifier of the opposite communication party. The method comprises a step in which the device connected to one opposite communication party receives the parameters from the one communication party and records the parameters, a step for transmitting the parameters recorded by the device connected to the other opposite communication party to the other opposite communication party, and a step for using the transmitted parameters to perform communication between the one opposite communication party and the other opposite communication party and confirming that the parameters are correctly shared.
