Method for generating high-entropy shared password between intelligent devices in short-distance wireless environment

The invention discloses a method for generating a high-entropy shared password between intelligent devices in a short-distance wireless environment. The method comprises the following steps: firstly,initializing a system and releasing system parameters; then, generating random variables based on short-distance wireless channel characteristics; then establishing a security sharing variable on a protocol selection frequency based on the identity and the random variable; and finally, generating a high-entropy sharing password based on the security sharing variable. The password generated by themethod can be used for authentication, so that the safety and reliability of communication between the short-distance wireless devices are improved. The protocol is suitable for application scenariossuch as a wireless Internet of Vehicles network and a wireless smart home network. 本发明公开了一种短距离无线环境下智能设备间的高熵共享口令生成方法，首先系统初始化及系统参数发布；然后基于短距离无线信道特征的随机变量生成；接着基于身份、随机变量在协议选定频率上建立安全共享变量；最后基于安全共享变量，生成高熵共享口令。本发明生成的口令可以作为认证使用，从而提高短距离无线设
