Title: Method for preventing furtive use of home bus system
Inventor: ONO YUKIKO
Filed: 1985-12-20
Abstract: PURPOSE:To prevent the furtive use of a home bus system by checking the transmission source address of a received communication packet in a communication controller and transmitting a signal, which invalidates this packet, to an information transmission medium if said address is equal to the address of this controller itself. CONSTITUTION:Off-hook of a telephone 52 is detected by even a communication controller 51 which is not recognized in a home bus, and the communication controller 51 tries to transmit an off-hook command. First, transmission source address '10' is transmitted through an information transmission medium 8 and is received by a home bus controller 50, and it is received even by the communication controller 1 and is compared with the address of this controller 51 itself. Since the received address is equal to its own address '10', the high level is outputted from a controller 2 for a period corresponding to 2 bytes at the time, when the next destination address is transmitted, to set the information transmission medium 8 to the high level so that the packet is invalidated. Thus, reception error is detected in the home bus controller 50, and the communication packet of the off-hook command from a communication controller 51' is invalidated and is not processed.
