A Distributed Login Framework for Semi-Structured Peer-to-Peer Networks

In Peer-To-Peer (P2P) networks, security is a challenging issue due to decentralization. In this paper, the authors propose an effective distributed login framework for P2P networks. User profile availability is a critical issue in P2P networks. Within the distributed login framework, they propose a new Reed-Solomon erasure code scheme leveraging the Pascal matrix that can guarantee user profile availability. Their performance and security analyses show that: the distributed login framework provides high availability and low redundancy rate; and the new erasure code has low computation and memory overheads.
