In this paper, a novel secure key sharing and distribution scheme for network mobility (NEMO) group communications is proposed. The scheme offers the capability of multiple key sharing and distribution for current and future application scenarios, and a threshold mechanism that effectively improves flexibility and robustness of the key sharing and distribution process. Both forward and backward secrecy are guaranteed by compulsive key refreshment and automatic key refreshment mechanisms, which provide dynamic in-progress group communication joining/leaving and periodic keys renewal, respectively. Security and performance analysis are presented to demonstrate that the proposed scheme meets the special security requirements for NEMO group communications and is competent for key sharing and distribution service
