Secure tunnelling of a frame in an in-vehicle communication network

An in-vehicle communication network controller, comprising:

• one or more components configured to:
• receive a set of messages provided by one or more network nodes included in an in-vehicle communication network;
• identify one or more message freshness values associated with determining a tunnel frame freshness value, the one or more message freshness values being included in a corresponding one or more messages of the set of messages;
• determine the tunnel frame freshness value based on one or more message freshness values;
• and
• generate a tunnel frame, the tunnel frame including the tunnel frame freshness value and the set of messages.

An in-vehicle communication network controller, comprising:

• one or more components configured to:
• receive a set of messages provided by one or more network nodes included in an in-vehicle communication network;
• encrypt a set of headers associated with the set of messages to generate a set of encrypted headers associated with the set of messages,
• each header in the set of headers being encrypted separately from other headers in the set of headers;
• and
• generate a tunnel frame, the tunnel frame including the set of encrypted headers and the set of messages.
