Anonymity in Peer-to-Peer network means that it is difficult to associate a particular communication with a sender or a recipient. Recently, anonymous Peer-to-Peer framework, called GNUnet, was developed. A primary feature of GNUnet is resistance to traffic-analysis. However, K"ugler analyzed a routing protocol in GNUnet, and pointed out traceability of initiator. we propose an alternative routing protocol applicable in GNUnet, which is resistant to K"ugler's shortcut Attacks.
