A device authentication and key agreement method for body area network based on channel characteristics

Abstract

The invention discloses a body area network device authentication and key negotiation method based on channel characteristics, which mainly includes five processes of initialization, device fingerprint generation, key negotiation, key authentication and key update, and utilizes the randomness of environmental factors As well as the uniqueness of user behavior characteristics, a device fingerprint is generated. The initialization process is used to establish the initial connection of the new device with the control unit in the system. The device fingerprint generation process is used to generate device fingerprints in preparation for the key agreement and key authentication processes. The key agreement process is used to generate an agreed session key between the new device and the control unit. The key authentication process is used to verify whether a device newly added to the system is a security device. The key update process is used to generate a unified session key for all BAN devices in the system and update it in time to ensure communication security and lightness of the key agreement protocol. The body area network device security authentication method provided by the present invention is more convenient, effective, safe and reliable.
