Original Abstract Submitted
A wireless interface includes: network formation circuitry configured to establish a wireless network between a primary node and a secondary node; data exchange circuitry configured to perform data exchanges between the primary node and the secondary node using secure sessions; and key refreshment circuitry configured to derive a new network key for the network based on a pre-shared key and a current network key concatenated with a session count. The new key is derived during at least one of the secure sessions.
