简单的异步（t,m,n）组认证方案
Simple asynchronous (t,m,n) group authentication
摘要
Abstract
Based on (t,n) threshold secret sharing, this paper proposes a simple asynchronous (t,m,n) group authenti-cation scheme to verify whether all participants belong to a pre-defined group at once. In the scheme, each user uses a sin-gle share as the token. Each participant constructs a component to bind the token with all m participants and recovers the secret with all components to check whether all participants are legal. Moreover, the scheme does not depend on any pub-lic key system. Analyses show the proposed scheme can resist up to t-1 insiders conspiring and outsiders with no more than m-1 components. Compared with Harn’s group authentication scheme, the proposed scheme is simpler, more effi-cient and flexible.关键词
