A method for data transfer in a network that comprises a lower network layer (LL), an intermediate network layer (IL), and a higher network layer (HL), at least one first device (D 1, USB-D) providing first transmission data (T-DATA- 1 ) of a first standard (USB) within said lower network layer (LL), at least one second device (D 2, BT-D) receiving second transmission data (T-DATA- 2 ) of a second standard (BT) within said lower network layer (LL), said method comprising the following steps: a first receiving step wherein said first transmission data (T-DATA- 1 ) of said first device (D 1, USB-D) are received within said lower network layer (LL), a first lower layer processing step (LLPS- 1 ), wherein said first transmission data (T-DATA- 1 ) are processed thereby generating first intermediate layer data (IL-DATA- 1 ) of said intermediate network layer (IL), a first intermediate layer processing step (ILPS- 1 ), wherein said first intermediate layer data (IL-DATA- 1 ) are processed thereby generating higher layer data (HL-DATA) of said higher network layer (HL), a second intermediate layer processing step (ILPS- 2 ), wherein said higher layer data (HL-DATA) are processed thereby generating second intermediate layer data (IL-DATA- 2 ) of said intermediate network layer (IL), a second lower layer processing step (LLPS- 2 ), wherein said second intermediate layer data (IL-DATA- 1 ) are processed thereby generating said second transmission data (T-DATA- 2 ), wherein said first intermediate layer processing step (ILPS- 1 ) comprises a security function (SF) ensuring that said higher layer data (HL-DATA) are conform with a predetermined security level, and/or wherein said second layer processing step (ILPS- 2 ) comprises said security function (SF- 2 ) ensuring that said second intermediate layer data (IL-DATA- 2 ) are conform with said predetermined security level.
