The invention relates to a terminal bidirectional verification method based on a low-frequency time code time service technology, which depends on the low-frequency time code time service technology, obtains standard time information by receiving a BPC time service device of a national time service center, and ensures that the time information received by terminal equipment is absolutely correct through a credible space-time platform and a time and position information processing end. Through a reverse verification mechanism, the time and position information is prevented from being tampered in the transmission process, and the requirements of source credibility, use credibility, information traceability, time propagation authentication and the like are met. 一种基于低频时码授时技术的终端双向验证方法，依托低频时码授时技术，通过接收国家授时中心BPC授时装置，获取标准时间信息，再通过可信时空平台和时间及位置信息处理端，保证终端设备接收到的时间信息是绝对正确的，另外，通过反向校验验证机制，避免时间及位置信息在传输的过程中被篡改，满足来源可信、使用可信、信息可溯源和时间传播可认证等要求。
