PROVIDING SECURE COMMUNICATIONS FOR ACTIVE RFID TAGS

摘要

Described herein in an example embodiment, is a mechanism to distribute and implement secure credentials on a WLAN (wireless local area network) employing radio frequency identification (RFID) tags. Symmetric keys are provisioned to the tag in a manner that allows for optimized re-association and secure announcements. The provisioned keys are derived in a way that enables the controller to operate without having to maintain the key state for every tag. In an example embodiment, the controller generates keys for the RFID tags that are derived from a master key associated with the controller, an identifier assigned to the RFID tag and an address associated with the RFID tag.
