On-line Secret Sharing Scheme Based on Elliptic Curve
基于椭圆曲线的在线秘密分享*

In this paper, we propose an on-line secret sharing scheme based on elliptic curve. This scheme is high-efficiency and security. It is able to detect and identify cheaters no matter how many the participants are dishonest . It provides the property to share multiple secrets and allows participants to be added/deleted dynamically, without having to update the shares of the existing participants, only updating some authentic information on the notice board.
