内容記述
Since the problem of disclosing personal information on the Internet continues to increase, many anonymous communication systems have been studied. Such systems usually use directory servers to manage the public keys of participant nodes and such node information as IP address, port number, and NodeID. However, this reduces anonymity because the query messages for the directory servers can give adversaries route information of anonymous communication channels. To solve this problem, applying ID-Based Encryption has been proposed, but in the existing method, directory servers continue to exist. Our novel method, which can grasp assigned NodeIDs without directory servers, can be applied to existing Distributed Hash Table (DHT)-based anonymous communication systems. Our proposal enhances scalability. This paper describes the structure of our proposed system and its application.
