An efficient proactive RSA scheme for large-scale ad hoc networks

<正>A previous proactive RSA scheme for large-scale ad hoc network has been shown to be faulty.In this paper,we present a new proactive RSA scheme for ad hoc networks,which includes four protocols:the initial key distribution protocol, the share refreshing protocol,the share distribution protocol,and the signature generation protocol.This scheme has two advantages:the building blocks are secure,and the system is efficient.
