基于概率的保持前缀地址随机化算法的安全评估

Probability Analysis Based Prefix Preserving IP Address Anonymization Scheme Security Evaluation

地址随机化算法通常用于在发布流量数据之前进行去隐私处理.保持前缀地址随机化算法就是其中一个常用算法.对于保持前缀地址随机化算法而言,由于引入了更多的限制,因此也面临更多的安全风险.分析了相关性攻击对保持前缀地址随机化算法的安全影响,并利用概率分析和仿真评估了不同攻击方法对其安全性能的影响.

IP address anonymization scheme is often used to avoid privacy issues before traffic distribution. Prefix preserving IP address anonymization scheme is one of the most frequently used schemes. For prefix preserving IP address anonymization scheme, more security threats are introduced because of more correlations, In this paper the correlation based security attacks are evaluated and different attack methods are studied with the probability model and simulation.
