A communication system and method for securely and efficiently sharing a link key for security and authentication in a ZigBee network. Upon receipt of an access request from an end device, a trust center sends a public key to the end device, and upon receipt of the public key, the end device encrypts an arbitrary key using the public key, and sends the encrypted arbitrary key to the trust center. The trust center generates a link key using the arbitrary key, and sends the link key to the end device. |
