Peer-to-peer anonymous networks offer the resources to support today's Internet applications. In today's dynamic networks, the key challenge to these systems arises from node dynamics and failures that disrupt anonymous routing paths, forcing them to be frequently rebuilt. Not only do these path rebuilds interrupt application sessions, but they also leak information to logging attacks such as the predecessor attack, leading to significant degradation of anonymity over long sessions. In this paper, the authors propose Bluemoon, a new anonymous protocol that provides strong resilience against the predecessor attack through the use of persistent anonymous links called hooks. When chained together, these links create robust anonymous paths that avoid path disruptions and rebuilds across node failures.
