Abstract: | In this paper, we propose a framework of cheating-detectable threshold schemes against the most powerful cheaters. Our scheme is used to distribute long secrets, and the share size is almost optimum. If the threshold is 2, our scheme is more efficient than the existing schemes even in the weaker adversarial model. |
