Efficient Secured Public-Key based Data Lookup and Multicast Protocols with Anonymity in RC-Based Two-level Hierarchical Structured P2P Network

Abstract

Because peer-to-peer networks are inherently insecure, they provide a special chal- lenge in terms of network security. In this study, we have considered a recently described non-DHT-based 2-level structured P2P network. It is an architecture built on interests. Utilizing RC, a modular arithmetic-based residue class, the overlay topology has been achieved. This design was chosen because it allows for minimal latency in both intra and inter-group communications. In the present study, we provide efficient schemes for public- key cryptographic security of existing communication protocols. We have also extended these approaches to include anonymity.
