PROBLEM TO BE SOLVED: To make it possible to store the message without deleting the message which does not want to be seen by a 3rd party by making impossible to read out and display the message for the people except the people knowing this cipher, adding the cipher to the received message. SOLUTION: A received radio selective calling signal is demodulated by a radio section 2 and given to a decoder 3. The decoder 3 compares a call number (ID) from a radio section 1 with its own call number received from a ROM 5 via a memory control section 4. When they are coincident, a message signal in succession to the ID is fed to the control section 4 from the decoder 3. The control section 4 stores the message signal to a RAM 6 and a display section 9 displaces the message signal. When the user desires security on this message from other party, a cipher information input section inputs cipher, the message stored in the RAM 6 is transferred to a ciphering message memory 7 together with the cipher. |
