Patent ID: 7840798

Claim:
A method for data transfer in a network, said network comprising a lower network layer, an intermediate network layer, and a higher network layer, at least one first device providing first transmission data of a first standard within said lower network layer, at least one second device receiving second transmission data of a second standard within said lower network layer, said method comprising: receiving said first transmission data of said at least one first device within said lower network layer, processing said first transmission data thereby generating first intermediate layer data of said intermediate network layer, processing said first intermediate layer data thereby generating higher layer data of said higher network layer, processing said higher layer data thereby generating second intermediate layer data of said intermediate network layer, and processing said second intermediate layer data thereby generating said second transmission data received by said at least one second device, wherein at least one of said processing said first intermediate layer data and said processing said higher layer data comprises a security function, at least one of said first transmission data, said first intermediate layer data, said higher layer data, said second intermediate layer data, and said second transmission data comprises at least one command or action that allows to control said at least one second device by said at least one first device or vice versa, and said security function comprises a blocking or a modification of said at least one command or action.
