Data secure transmission method for wearable equipment

The invention provides a data secure transmission method for wearable equipment. The data secure transmission method comprises six steps of channel detection, channel data preprocessing, quantization and coding, information coordination, confidentiality enhancement and secure data transmission. According to the data secure transmission method, the first five steps are mainly that a shared key is generated among legal nodes by using wireless channel data, and the sixth step is that the data is encrypted among the legal nodes by using the shared key, so that the confidentiality of the transmitted data is ensured; and when the key is found to be invalid or the number of times of use reaches a preset value during secure data transmission, the legal nodes can discard the current key and restart the previous process to generate a new key to complete subsequent secure data transmission. The data secure transmission method can be widely applied to various edge computing application scenes, can improve the efficiency
