| 摘 要： | A secret sharing system can be damaged when the dealer cheating occurs. In this paper,two kinds of secret sharing schemes based on linear code are proposed. One is a verifiable scheme which each participant can verify his own share from dealer‘s distribution and ensure each participant to receive valid share. Another does not have a trusted center, here, each participant plays a dual-role as the dealer and shadow(or share) provider in the whole scheme.
