摘要
针对车载自组织网络风险评估过程中存在的复杂性和影响因素的不确定性,提出采用区间层次分析法对VANET进行安全风险评估。该方法通过用区间数给出专家评分等级区间并计算出风险因素的相对权重,增强对网络安全风险评估结果的可信度。以位置信息威胁为实例并进行仿真实验,结果表明在VANET安全风险评估中采用区间层次分析法是一种更加科学的、更加客观的方法。
Aiming at the complex and the uncertainty of influencing factor in the process of vehicle Ad Hoc network security risk assessment. Proposes a network security risk assessment method based on Interval Analytical Hierarchy Process. The method uses interval data to delimit expert judge degrees and computes the relative weight of the risk factors, it boosts up reliability of e- valuation result in network security risk assessment. The simulation based on the attack of the location information shows that this method is one kind of more scientific and the more objec- tive method in VANET security risk assessment.
