A secure and Efficient (t, n) Multisecret Sharing Authenticating Scheme
一种安全有效的（t, n）多秘密共享认证方案

A secure and efficient (t, n) multisecret sharing authenticating scheme based on double shadow is proposed. The main merits are that the participant can reuse his shadows to recover the sharing multiple secrets that the dealer given and it only needs three parameters to reconstruct one secret, and need not to perform a zero-knowledge protocol to prevent the participant cheating. The proposed scheme is clearly superior to the other existing schemes in terms of both computational costs and communication costs.
