摘要：PROBLEM TO BE SOLVED: To provide a radio communication cipher system where the protection of privacy is necessitated. SOLUTION: The ratio communication cipher system 110 where the protection of the privacy is necessitated transmits a ciphered signal between a base station 112 and a radio terminal 122. At a forward channel the base station 112 includes a long code mask generator generating a rotating long code mask and also a ciphering device. A radio terminal 124 similarly includes the long code mask generator generating the rotating long code mask and also a deciphering device.
