- Implement secure transport mechanisms in `gateway_knx_secure_transport.cpp` for handling secure sessions, including AES encryption, session key generation, and secure packet wrapping and unwrapping. - Introduce `OamRouterRuntime` in `oam_router_runtime.cpp` to manage OAM router identity, individual addresses, and tunnel frame handling. - Enhance secure session management with functions for session allocation, authentication, and secure packet processing. - Ensure compatibility with existing KNXnet/IP protocols while adding support for secure communications.
