At present, smart watches are loved by users because of their convenience, high efficiency, aesthetics and practicality. Smart watches interconnect with matching smart phones instead of working individually to achieve their maximum functionality. The wireless network interface serves as an interconnection bridge between smart watches and smart phones to realize application data exchange, which introduces a risk to personal security and privacy. Therefore, improving Wi-Fi firmware security is very important. To boost the security of the wearable device, we propose a security upgrade and replacement scheme of the Wi-Fi firmware by expanding the security function of the Wi-Fi watch firmware and a reliable replacement method, which can effectively improve the security of the smart watch. We implement firmware switching and recovery at the kernel level. Data encryption module is added to the firmware to enhance data interaction security. Experiments show that our approach improves robustness of Wi-Fi firmware upgrade and data interaction security while guarantees the ordinary functionality of the Wi-Fi module.
