Intelligent terminal authentication method based on multi-mode sensing and intelligent terminals

The invention discloses an intelligent terminal authentication method based on multi-mode sensing and intelligent terminals. The method includes the steps that identical environmental effects are applied to all the intelligent terminals, and each intelligent terminal collects a sensor characteristic value of its own in real time; later, the sensor characteristic values of all the intelligent terminals are broadcasted in a wireless network in sequence, each intelligent terminal conducts similarity matching on a received characteristic value and itself after receiving a broadcasted characteristic value, and if matching is successful, a common secret key is generated; all the intelligent terminals use the secret key to achieve data transmission. Each intelligent terminal comprises a multi-mode sensing data collection and pre-processing module, a data communication module, a sensing data matching and authentication module and a secret key generation module. Through the method, a multi-mode sensing and authentication mechanism is obtained through an acceleration sensor and a gyroscope sensor, and the intelligent terminals can conduct communication with adjacent intelligent terminals in an unsafe wireless network channel.
