总线网络取证信息自动检索风险控制系统设计

Design of risk control system for automatic retrieval of bus network forensics information

摘要:

当前取证信息自动检索系统未对取证信息潜在检索风险进行过滤,导致对取证信息的检索风险控制效果差、检索效率低、误差高的问题,为此设计一种总线网络取证信息自动检索风险控制系统。将输入的取证信息在采集模块中进行收集,检索风险控制模块对采集的取证信息信息进行风险过滤和风险控制后,发送给DSP进行自动检索,采用STM32F407设计接口电路连接采集模块和检索风险控制模块,完成硬件部分的改进；选择高检索相关度节点,利用节点内置文档实现取证信息检索风险的控制,完成软件部分设计。实验结果表明,该系统的检索风险控制效果好,控制精度可达到80%以上,能够为用户提供更有效、更安全的权证信息检索结果。

Abstract:

At present, the automatic retrieval system of forensics information does not filter the potential retrieval risk of forensic information, which leads to the problem of poor control effect, low retrieval efficiency and high error. Therefore, a system of automatic retrieval of risk control system of bus network forensics information is designed. After collecting the input information in the acquisition module, the risk control module is sent to the DSP for automatic retrieval after the risk filtering and risk control of the collection information information. The STM32F407 design interface circuit is used to connect the acquisition module and the risk control module to complete the improvement of the hardware part. It selects high degree of retrieval relevance node, uses node built-in documents to achieve the control of risk of forensic information retrieval, and completes the software part design. The experimental results show that the system has a good control effect and a control precision of more than 80%. It can provide more effective and safer information retrieval results for the users.
