摘要：

【目的】 IP地址作为网络层的唯一标识符,已经成为网络追踪和隐私关联分析的基础信息。区别于其它个人可识别标识,耦合了身份与位置隐私的IP地址作为路由寻址必备信息,不得不暴露在IP报文头部,从而难以采用终端侧的混淆技术消除IP隐私泄露风险。【方法】 为了保护IP隐私,本文提出了一种终端设备与网络设备协同的IP隐私保护技术方案。【结果】 在该方案中,网络设备对IP地址等隐私信息进行实时混淆,能够达到逐包级的IP隐私保护,防止隐私好奇者通过窃听或收集IP报文来实施隐私攻击。该技术在同时兼顾隐私保护、路由高效寻址、审计追踪等需求的情况下,不但消除当前IP地址耦合身份和位置双重语义的障碍,而且还对身份标识符和位置标识符分别进行加密保护。【结论】 本文的技术可以对IP隐私进行较好的保护,具有很高的潜在实用价值。

Abstract:

[Objective] As the unique identifier of network layer, IP address has become the basic information of network tracking and privacy correlation analysis. Different from other personal identifiers, the IP address coupled with identity and location privacy is the necessary information for routing addressing, and has to be exposed in the IP header, so it is difficult to eliminate the risk of IP privacy leakage by using terminal side obfuscation technology. [Methods] In order to protect IP privacy, we propose a technology based on the cooperation between terminal devices and network devices. In this scheme, IP address and other private information can be obfuscated by network devices in real-time. [Results] The proposed method can achieve packet-by-packet IP privacy protection and prevent privacy curious attackers from eavesdropping or collecting IP messages to implement privacy analysis. This technology not only eliminates the barrier of dual semantics of the current IP address coupling identity and location, but also encrypts the identity and location identifiers separately while meeting the requirements of privacy protection, efficient routing addressing, and auditing and tracing. [Conclusions] The technology in this paper can give IP privacy a good protection, so we think it may have high potential practical value.
