Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] Such as figure 1 As shown, a schematic diagram of the combination of the body area network and the health blockchain in the present invention is given. The body area network is a wireless sensor network formed by gateway nodes and physiological sensor nodes through a specific network protocol.

[0025] Among them, the gateway node has more operating resources, is deployed outside the human body, and is generally served by a portable device (such as a PDA). The gateway device has sufficient energy, computing power, storage unit, communication unit and other resources. It can use the built-in IEEE802.15.6 module to communicate with the physiological sensor node, receive the data sent by the physiological sensor node, and send data to the physiological sensor node Send data and commands. At the same time, the gateway device can use the GPRS\3G\4G ...

Abstract

The invention provides a lightweight back-up and efficient restoration method of health block chain data encryption keys.Body area networks achieve physiological parameters acquisition of healthy body health, health block chains are produced by a group of credible IT devices appointed by multiple health institutions and used for receiving and storing health data of the body area networks, the health block chain data encryption keys are produced by utilizing a fuzzy technology fuzzy vault and physiological signals acquired by the body area networks, human physiological data acquired in different time periods is encrypted by utilizing different data encryption keys and then is saved in the block chains of the IT devices without storage of historical data encryption keys; historical secret keys are restored by utilizing the health data acquired by the body area networks in real time.The lightweight back-up and efficient restoration method integrates the body area networks with the health block chains, avoids huge burden brought by secret key splitting related in a traditional secret key restoration method and safe storage and retrieval of shadow secret keys and greatly reduces management complexity of the health block chain data encryption keys.

Description

technical field [0001] The present invention relates to a lightweight backup and efficient recovery method for a healthy blockchain data encryption key, and more specifically, to a method capable of avoiding key splitting and shadow encryption involved in traditional key recovery methods. The huge burden brought by the safe storage and retrieval of keys greatly reduces the complexity of key backup and recovery. A lightweight backup and efficient recovery method for healthy blockchain data encryption keys. Background technique [0002] Blockchain is a technology that uses Hash chains with digital signatures to realize accounting consensus and distributed storage, and can ensure the traceability and non-tampering of ledgers. It originated from an electronic currency system designed by Satoshi Nakamoto in 2008. However, in recent years, the huge application value of this technology in the fields of intelligent health and finance has gradually been recognized by the industry, an...
