摘要: 利用双变量单向函数提出了一种多重秘密共享体制。由于该方案的秘密份额由共享者自己选择,秘密分发者不需要向他们传送任何秘密信息,所以不需要安全信道。同时,各共享者可以验证其他共享者秘密伪份额的正确性并且秘密份额可以重复使用,离线验证。

Abstract: A new multiple secrets sharing scheme based on two variable one-way function is proposed,which is able to guard against cheating among participants.Because each participant chooses his own shadow by himself,the system doesn’t need a security channel.Meanwhile,each cooperative participant can check the other’s pseudo-shadow that is true or not.Due to the same fact,participants’ shadows remain secret can be reused,even all sub-shadows are made public.

Key words: secret sharing, threshold scheme, two variable one-way function, verifiable
