摘　　要：基于车载远程信息处理器(T-BOX)的数据取证方法主要针对T-BOX与手机APP等之间网络数据流,缺乏针对T-BOX底层数据的分析取证方法研究。针对该问题,提出一种基于T-BOX数据逆向分析的车辆行为取证算法。该算法主要分为数据预处理、底层数据解析及行驶行为重塑3个阶段。数据预处理阶段通过设置车辆静止数据标识及典型数据阈值范围,对原始数据进行清理;底层数据解析阶段通过数据类型识别及数据描述转换,完成不同模块数据解析;行驶行为重塑阶段实现车辆行程数据分析及车辆行驶路径重塑。实验结果表明,基于T-BOX数据逆向分析的车辆行为取证算法能够有效实现车辆行程数据分析及车辆行驶路径重塑,相较于传统TBOX数据取证方法,取证结果更加完整、准确,同时避免了T-BOX数据无线传输的安全性问题。The existing data forensics methods based on Telematics BOX(T-BOX)are mainly aimed at the network data flow between T-BOX and mobile APP,etc.,and no evidence analysis and forensics methods for the underlying data of T-BOX have been found.A vehicle behavior forensics algorithm based on T-BOX data reverse analysis is proposed.The algorithm is mainly divided into three stages:data preprocessing,underlying data analysis and driving behavior reshaping.In the data preprocessing stage,the original data is cleaned by setting the vehicle stationary data identification and typical data threshold range.In the underlying data analysis stage,the data analysis of different modules is com-pleted through data type identification and data description conversion.In the stage of driving behavior reconstruction,vehicle travel data analysis and vehicle driving path reconstruction are realized.The ex-perimental results show that the vehicle behavior forensics algorithm based on T-BOX data reverse analysis can effectively realize vehicle travel data analysis and vehicle path reshaping.Compared with the traditional T-BOX data forensics method,the forensics results are more complete and accurate,and at the same time,the security problem of wireless transmission of T-BOX data is avoided.
