Scalable Byzantine fault tolerant public key authentication for peer-to-peer networks

Peer-to-Peer (P2P) communication model has the potential to harness huge amounts of resources. However, due to the self-organizing and self-maintaining nature, current P2P networks suffer from various kinds of attacks. Public key authentication can provide a fundamental building block for P2P communication security. In this paper, we propose a scalable Byzantine fault tolerant public key authentication scheme for P2P networks, in which each participating peer dynamically maintains a trusted group to perform distributed challenge-response anthentication without centralized infrastructure. To guarantee the authentication correctness, we additionally present a complementary trusted group maintenance scheme. The experimental results demonstrate that our authentication scheme can work in various different P2P scenarios effectively and efficiently.http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000259084900056&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701Computer Science, Hardware & ArchitectureComputer Science, Theory & MethodsEICPCI-S(ISTP)
