Arapinis等人[1]最近提出了对3G移动的电话安全操作的修改，以解决新发现的对用户隐私的威胁。在本文中，我们严格审查这些修改。这一分析表明，拟议的修改在许多方面都不切实际;不仅存在安全和执行问题，而且对系统运作的必要改动也非常重大，远远超出预期。事实上，如果不彻底重新设计安全系统，一些隐私问题似乎几乎不可能解决。尽管修改已经使用基于逻辑的建模工具进行了验证，但所提出的“修复”存在缺点，这表明需要非常小心地使用这些工具。
Arapinis et al. [1] have recently proposed modifications to the operation of 3G mobile phone security in order to address newly identified threats to user privacy. In this paper we critically examine these modifications. This analysis reveals that the proposed modifications are impractical in a variety of ways; not only are there security and implementation issues, but the necessary changes to the operation of the system are very significant and much greater than is envisaged. In fact, some of the privacy issues appear almost impossible to address without a complete redesign of the security system. The shortcomings of the proposed ‘fixes’ exist despite the fact that the modifications have been verified using a logic-based modeling tool, suggesting that such tools need to be used with great care.
