摘要 该文提出了一种基于内插多项式的广播加密方案,消息发布者通过管理中心指定多个信息接收者,管理中心生成一个内插多项式,并公布相关的信息,合法用户根据自己的秘密信息和中心公布的消息,通过计算线段的中点来得到内插多项式,达到安全广播加密的目的。 A broadcast encryption scheme based on the interpolating polynomial is proposed. It allows the sender to designate multi-receivers to the Authority Center （AC）. The interpolating polynomial is constructed and the related information is proclaimed by AC. The interpolating polynomial can be reconstructed by computing the central point of line segment to achieve the purpose of broadcasting safely by the legal users using their secret information and the public information published by AC.
