Abstract

Group authentication aims at facilitating efficient authentication of a group of provers by a group of verifiers. A new group authentication scheme is proposed to improve the security of existent asynchronous group authentication schemes and to achieve better computational performance. The new scheme allows any groups of legitimate members to execute multiple authentication trials even under the participation of active attackers.
