A Broadcast Encryption Scheme Based on the Interpolating Polynomial
一个基于内插多项式的广播加密方案

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.
