摘要：
In this paper, we point out flaws in existing secret sharing schemes against cheating. Namely, we show that a scheme proposed by Ghodosi and Pieprzyk presented at ACISP 2000 and a one by Obana and Araki presented at Asiacrypt 2006 are both insecure against single cheater. We further show that the scheme by Obana et al. can be made secure by slight modification.
