A Novel Universally Composable Threshold Signature Protocol for Mobile Ad-Hoc Network

Mobile ad-hoc network has received a lot of attention recently, adapting threshold signature schemes to work in such environments is challenging. In this study, we propose a novel threshold RSA signature protocol. The proposed protocol is suitable for the mobile ad-hoc networks, for it is completely non-interactive and has simple algorithm. Furthermore, we will give the concrete analysis of the reduction to prove the security of the proposed protocol. The proposed protocol is also secure under the universal composability framework, it can be applied to the mobile ad-hoc networks regardless what the environment it interacts with.
