摘要: 基于MIX匿名系统模型,提出一种改进的统计命中集攻击算法,并在该算法的基础上给出基于填充包的防御策略。理论分析和实验结果表明,与已有的统计命中集攻击相比,该攻击在接收者相对集中时有较好的攻击效果,采用填充包技术能有效地降低攻击的准 确性。

Abstract: This paper proposes an improved Statistical Hitting Set attack(SHS-attack) based on MIX anonymity technique and a defence strategy based on dummy packets to counter against this attack. Theoretical analysis and simulations show that, this attack is more efficient than previous SHS-attack while all the recipients congregate in a small group and the dummy packet technique can effectively decrease the accuracy of this attack.

Key words: data privacy, network security, anonymous communications, Statistical Hitting Set attack(SHS-attack)
