    • When a common key is updated to a new common key, it is possible to prevent the generation of a period during which not all the general communication apparatuses are enabled to make mutual communications using encrypted data while at the same time reducing the memory consumption of the general communication apparatus. A common key control apparatus 11 transmits a first status transition request R1 to all the general communication apparatuses when all the general communication apparatuses 12 made a transition to a distribution completed status, and transmits a second status transition request R2 to all the general communication apparatuses when all the general communication apparatuses 12 made a transition to an in-transit status. The general communication apparatus 12 makes a transition from the update completed status to the distribution completed status upon receipt of a new common key from the common key control apparatus 11, while it makes a transition from the distribution completed status to the in-transit status upon receipt of the first status transition request and it restores the state to the update completed status from the in-transit status upon receipt of the second status transition request.

    • The invention provides a router device, a communication device, a routing method, a routing program, and a computer-readable recording medium recorded with the routing program that enable to improve communication efficiency. The communication data receiving section 10 receives communication data from the high-speed transmission medium 2. The communication data storage 11 stores the received communication data therein. The communication data sending section 12 sends the communication data to the low-speed transmission medium 3. The communication data temporal storage 13 temporarily stores the communication data sent from the communication data sending section 12 therein. The destination comparing section 14 compares the destination of the communication data stored in the communication data storage 11 with the destination of the communication data stored in the communication data temporal storage 13. The communication data transmission controlling section 15 designates the communication data sending section 12 to send the communication data stored in the communication data storage 11 if a comparison result by the destination comparing section 14 indicates destination matching or if no communication data is stored in the communication data temporal storage 13. The communication data erasing section 16 erases the transmitted communication data from the communication data storage 11.

    • In a communication system in which both a communication device that does not operate intermittently and a communication device that operates intermittently are present, high-speed communications between the communication devices are enabled while achieving power saving in the communication device that operates intermittently. A transmission processing portion 102 that transmits various kinds of data, a timer portion 107 that counts a continuous operation request effective time during which transmitted data is always received, a transmission control portion 104 that controls the transmission processing portion 102 to transmit data in which is set a continuous operation request flag causing the timer portion 107 in a communication device 11 that operates intermittently to start counting the continuous operation request effective time while starting its own timer portion 107 to count the continuous operation request effective time, a reception processing portion 101, and a reception control portion 103 that controls the reception processing portion 101, are provided. Upon receipt of the data in which the continuous operation request flag is set at its own reception processing portion 101, the reception control portion 103 in the communication device 11 that operates intermittently controls its own timer portion 107 to start counting the continuous operation request effective time.
