Abstract:
A communication device comprises a receiver configured to receive a notification of a cipher parameter used for encryption of data and a requested start time at which the encryption starts; and a correction unit configured to determine whether the cipher parameter needs to be corrected in response to the notification having been retransmitted based on the requested start time and an actual start time at which the encryption actually starts, and correct the cipher parameter.
