Mobile Intelligent Terminal System Security Evaluation Method based on Graph and Topological Potential

智能终端安全威胁评估是终端安全工程的重要组成部分,对于制定系统安全策略具有重要意义。针对现在缺乏移动智能终端特点的安全评估方法的问题,使用基于图和拓扑势函数的移动智能终端安全威胁评估方法,通过计算威胁图中各个节点的熵值,确定其在威胁图中的重要程度,达到对移动智能终端进行安全评估的目的。最后采用上述方法进行了仿真,证明算法的可行性和正确性。后续对多类型和多数量的终端进行安全测评可利用边缘计算设备的计算资源,以实现对多个终端设备的客观准确评估。

Intelligent terminal security threat assessment,as an important part of terminal security engineering,is of great significance for the development of system security policies.Aiming at the lack of security assessment methods for mobile intelligent terminals,the mobile intelligent terminal security threat assessment method based on graph and topological potential function is proposed,which is used to determine the importance of each node in the threat graph by calculating the entropy value of each node in the threat graph,so as to achieve the purpose of security assessment for the mobile intelligent terminal.Finally,the above method is used to simulate and prove the feasibility and correctness of the algorithm.Subsequent security assessment of multiple types and numbers of terminals may utilize computing resources of the edge computing device and achieve objective and accurate evaluation of multiple terminal devices.
