【Abstract】With the development of sensor devices, wireless sensor networks have been widely used, and Wireless Body Area Networks (WBANs) are relatively common application scenarios in wireless sensor networks. The wearable device is used to collect physiological data of the human body, and the server device is adopted to store physiological data of the human body. The openness of the network environment and network devices' dynamic nature make WBANs vulnerable to security threats from attackers. The centralized two-hop architecture contains only one hub node, and the data stored in the hub node may be tampered with by attackers. Once attackers occupy the node, the entire network will be paralyzed. To tackle such an issue, it is proposed in this article a model in WBANs architecture based on Blockchain technology, where the authentication protocol and blind signature protocol between nodes are designed in the new WBANs model, making the Blockchain data transmission system in a wireless network environment secure and reliable. Experimental results show that the proposed method is promising and shows higher levels of safety and stability than other methods.
