我们为信息中心网络（ICN）设计了一个以内容为中心的隐私方案。我们通过将基于属性的加密引入ICN并使其特定于数据属性来增强ICN支持数据机密性的能力。我们的方法是不寻常的，因为它保留了ICN的目标，即解耦发布者和订阅者，以提高数据的可访问性，可扩展的多方通信和有效的数据分发。受应用层访问控制的启发，我们使用更具表现力的策略来实现细粒度的访问控制。此外，我们提出了一个基于属性的路由方案，提供利益的机密性。基于ICN的流行开源版本CCNx实现了一个原型系统，以展示智能社区和智能城市应用中的隐私保护。
We design a content-centric privacy scheme for Information-Centric Networking (ICN). We enhance ICN's ability to support data confidentiality by introducing attribute-based encryption into ICN and making it specific to the data attributes. Our approach is unusual in that it preserves ICN's goal to decouple publishers and subscribers for greater data accessibility, scalable multiparty communication and efficient data distribution. Inspired by application-layer publish-subscribe, we enable fine-grained access control with more expressive policies. Moreover, we propose an attribute-based routing scheme that offers interest confidentiality. A prototype system is implemented based on CCNx, a popular open source version of ICN, to showcase privacy preservation in Smart Neighborhood and Smart City applications.
