A RSA keys sharing scheme based on dynamic threshold secret sharing algorithm for WMNs

摘要

Wireless Mesh networks (WMNs) is a new wireless network with great potential application, its security is also affected by people's attention. Establishing a distributed virtual CA is an important tool to ensure the security of the wireless mesh networks. In these scenarios, several nodes jointly reserve the system's private key. This article proposes a RSA key sharing scheme based on dynamic threshold secret sharing algorithm. In this scheme, the child secrets that are saved by the shared nodes can be reused. When the shared nodes are changed, it is not necessary to repeat the procedures for distributing the child secrets.
