Feng Wang, Lize Gu, Yousheng Zhou, Yixian Yang, Yajian Zhou · 2010
In 2006, Jun et al presented a novel non-interactive verifiable secret sharing scheme constructed by Shamir's secret sharing scheme for secure multi-party communication protocol in distributed networks. In their scheme, the Dealer only publishes one commitment for verification. The efficiency of verification for each share doesn't fall as the augment of the threshold and the security of the verifiable secret sharing scheme is based on the intractability of computing discrete logarithm. So they demonstrated that their scheme can efficiently withstand not only the deceptive behavior between the Dealer and participants but among participants. In this paper, we analysis the security of their scheme and point out that their scheme couldn't resist the deceptive behavior like they claimed.
