Method for data transfer in a network

A method implemented by a gateway connectable with a network having a network signature, said method comprising:

• receiving and/or processing, with a presenter proxy module, first intermediate layer data, thereby generating higher layer data of a higher network layer, wherein said processing comprises a security function having a security function signature, said security function ensuring that said higher layer data conform with a predetermined security level;
• and
• receiving said higher layer data, and processing said higher layer data with an emulator proxy module, thereby generating second intermediate layer data of an intermediate network layer, wherein said processing said higher layer data comprises said security function, said security function ensuring that said second intermediate layer data conform with a predetermined security level;
• checking whether said security function signature and said network signature are compatible with each other;
• and
• impeding, with a processing unit implemented using hardware, a functioning and/or a loading of said emulator proxy module and/or of said presenter proxy module, if said security function signature and said network signature are not compatible with each other.

A non-transitory recording medium carrying a computer program, wherein the computer program, when executed by a processing unit, cause the processing unit to perform a method comprising:

• receiving and/or processing, with a presenter proxy module, first intermediate layer data, thereby generating higher layer data of a higher network layer, wherein said processing comprises a security function having a security function signature, said security function ensuring that said higher layer data conform with a predetermined security level;
• and
• receiving said higher layer data, and processing said higher layer data with an emulator proxy module, thereby generating second intermediate layer data of an intermediate network layer, wherein said processing said higher layer data comprises said security function, said security function ensuring that said second intermediate layer data conform with a predetermined security level;
• checking whether said security function signature and a network signature of a network connectable with the processing unit are compatible with each other;
• and
• impeding a functioning and/or a loading of said emulator proxy module and/or of said presenter proxy module, if said security function signature and said network signature are not compatible with each other.
