Abstract
A computer network may include a Non-IP subnetwork for communication between the gateway and the frontend device, an IP subnetwork for communication between the gateway and at least one backend device, and a gateway connecting the Non-IP subnetwork with the IP subnetwork and translating communication therebetween. The IP communication is based on an IP security protocol, providing means for authentication and/or encryption. The gateway mediates handshaking for establishing a secure tunnel for secure end-to-end communication between the backend device and the frontend device. The secure tunnel is set to apply a session key. The gateway and the backend device exchange datagrams with handshaking parameters. The Non-IP messages are exchanged with a subset of the handshaking parameters. The backend device and the frontend device generate the session keys and to authenticate the handshaking incorporating the handshaking parameters and subset of handshaking parameters, respectively.
