Jianzhong Zhang, Lan Jianqing · Jisuanji gongcheng · 2010
In existing scheme,the dealer chooses and delivers secret information to every participant,so a secure channel between them is necessary,and in the recovery phase,the scheme can not check whether every participant provides the true information.Aiming at such shortcomings,the paper proposes a verifiable multi-secret sharing scheme based on ECC.Each participant’s secret shadow is selected and kept by the participant himself.The shadows do not need to be changed when the shared secret is renewed,and many secrets can be recovered one time.The scheme can check whether each participant provides the true information,so a secure channel between them is unnecessary.
