PROBLEM TO BE SOLVED: To provide a radio communication method and a radio communication system in which secrecy of information to be sent/received between a master set and a specific slave set is enhanced. SOLUTION: A master set encrypts a hop table in the frequency hopping system through the public key system (step S8) by using a public key from a slave set (step S7) and transmits the information to the slave set (step S9), the slave set uses a private key to decode the information and then both the master set and the slave set share the hop table in common and send/receive information by the frequency whipping system (step S13). Furthermore, both the master set and the slave set are provided with a hop table generator ad send/receives only an initial value encrypted by the public key encryption system and generate the hop table by using the initial value. Moreover, a password used to identify the slave set is encrypted by the public key encryption system and the master set and the slave set send/receive the password. |
