Assignee: INVENTRONICS GMBH
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 9:
10. A frontend device for a computer network;
wherein the frontend device is configured to communicate with a gateway within a Non-IP subnetwork by applying a Non-IP communication;
wherein the gateway is configured to communicate with a backend device within an IP subnetwork by applying IP communication based on an IP security protocol, which provides means for authentication and/or encryption; and
wherein the frontend device is set to exchange data with the backend device via a secure tunnel for secure end-to-end communication, wherein the secure tunnel is set to apply a session key; and
wherein the frontend device is configured to run a limited implementation of the IP security protocol such that the frontend device is capable to interpret Non-IP messages with a subset of the handshaking parameters, provided from the gateway, which mediates handshaking for establishing the secure tunnel, to generate the session key.
