Secure and Efficient Membership Control for Ad Hoc Groups

The group membership dynamics and the lack of online trusted dealer make the secure membership control become an open challenge in ad hoc groups. The paper proposes a secure and efficient ID-based membership control scheme, which is non-interactive and verifiable in GMC issuance. Compared with other proposed solutions, the verifiability is only achieved in schemes using threshold DSA signature before, but which is interactive. The simulation results show the performance of proposed scheme is better than other solutions, especially in the hostile environment.
