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