命名数据网络（NDN）是以信息为中心的网络（ICN）愿景的一种实现，它提供了一种请求-响应通信模型，在该模型中，数据基于网络层的应用程序定义的名称进行标识。这增强了审查当局限制访问某些数据/网站/应用程序和监控用户请求的能力。大多数现有的基于NDN的框架都专注于使审查网络中的用户能够访问该网络之外的数据，而没有考虑审查网络中的数据生产者如何将其数据提供给该网络之外的用户。这个问题变得特别具有挑战性，因为NDN通信路径是对称的，而生产者必须签署他们生成的数据并识别他们的证书。在本文中，我们提出了Harpocrates，一个基于NDN的框架，用于在审查条件下发布匿名数据。Harpocrates使审查网络中的生产者能够生产并向这些网络之外的用户提供他们的数据，同时对审查当局保持匿名。我们的评估表明，Harpocrates在不同的设置下实现了匿名数据发布，能够识别和适应审查行动。
Named-Data Networking (NDN), a realization of the Information-Centric Networking (ICN) vision, offers a request-response communication model where data is identified based on application-defined names at the network layer. This amplifies the ability of censoring authorities to restrict access to certain data/websites/applications and monitor user requests. The majority of existing NDN-based frameworks have focused on enabling users in a censoring network to access data available outside of this network, without considering how data producers in a censoring network can make their data available to users outside of this network. This problem becomes especially challenging, since the NDN communication paths are symmetric, while producers are mandated to sign the data they generate and identify their certificates. In this paper, we propose Harpocrates, an NDN-based framework for anonymous data publication under censorship conditions. Harpocrates enables producers in censoring networks to produce and make their data available to users outside of these networks while remaining anonymous to censoring authorities. Our evaluation demonstrates that Harpocrates achieves anonymous data publication under different settings, being able to identify and adapt to censoring actions.
