基于IPFS的Tor隐藏目录服务研究

or Hidden Service allows service providers to provide Internet services without exposing their location, realizing two-way anonymity between client and server. Hidden Service Directory (HSDir) is the core component of Tor hidden service communication link, which handles publishing, subscribing and life cycle management of hidden service. However, currently, tor HSDir network is composed of onion routes with special flags provided by global volunteers, and attackers can destroy the anonymity of hidden services by deploying malicious nodes. For service scenarios of high-security requirements, it is particularly important to establish an autonomous and controllable HSDir network. In this paper, a tor HSDir model based on InterPlanetary File System (IPFS) is proposed, which is designed from three aspects: address rules, routing deployment and communication transmission. Experiments are designed to simulate the publishing and query process of hidden service, which verifies the feasibility and effectiveness of the model.
