Application of Tow Threshold Signature Schemes in P2P E-commence
Guangxue Yue · 2007
Based on JXTA,P2P E-commence situation grounding upon loosely consistent DHT lacks trusted center and may have a lot of malicious peers,so it is necessary for the system to introduce the credible analysis for new peer.An authentication and access control scheme applying RSA and DSA threshold algorithm is proposed.This scheme is adaptable to dynamic network,and can resist many kinds of attacks from malicious peers such as the conspiracy attack.It is theoretically proved that the security of system is enhanced.Simulation results indicate that the efficiency of peer recognition and the accuracy of authentication are increased.Simultaneously,threshold RSA is compared with threshold DSA on efficiency by experiment.
