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, we propose an effective distributed login framework for P2P networks. User profile availability is a critical issue in P2P networks. Within the distributed login framework, we propose a new Reed-Solomon erasure code scheme leveraging the Pascal matrix that can guarantee user profile availability. Our performance and security analyses show that: (1) the distributed login framework provides high availability and low redundancy rate; and (2) the new erasure code has low computation and memory overheads.
