Abstract
A network node may receive a control plane message. The control plane message may include an indication that the control plane message is a control plane message, an indication that the control plane message is associated with security, an indication of a security key to be associated with a secure zone (SZ) of an in-vehicle communication network, and an indication of a freshness value. The network node may perform a cryptographic operation for a data plane message associated with the SZ using the security key.
