Abstract
Cryptographic key management is a challenge for the large scale deployment of Internet of Things (IoT) devices. It is difficult to properly setup and constantly update keys for numerous IoT devices, especially when these devices are restricted by size and lack of the key input interface. This paper proposes a lightweight key management scheme which embeds the key distribution and update process into the communication process. The keys are constantly changing as the communication data flowing back and forth between IoT devices. Therefore even if a key is stolen by the attacker, it will quickly become invalid as the communication goes on. The proposed scheme also contains a key initialization protocol which generates independent keys for multiple IoT devices simultaneously. This paper describes the protocols in detail and analyzes its security properties. The practicality of the protocol is verified by experiments.
