Abstract
A wireless communication system and method includes a first wireless node and a data concentrator configured to provide a new encryption key updated from a current encryption key to the first wireless node. The data concentrator includes first and second transceivers. The data concentrator provides a key update message that includes the new encryption key to the first wireless node via the first transceiver. The key update message is encrypted using the current encryption key. The data concentrator is configured to decrypt first transmissions from the first wireless node via the second transceiver using the new encryption key, and decrypt the first transmissions via the first transceiver using the current encryption key.
