Secure and Verifiable Vector Space Secret Sharing Scheme

摘要：

This paper presents a method to detect cheatersefficiently with a trusted dealer distributing the secretinformation in the initialization phase and renewingphase by means of the intractability of quadraticresidue problem. The new vector space secret sharingscheme demands every participant verify the share hereceives and those other participants show. Whenuntruthful dealers appear, the scheme can also beextended to find them. Results indicate that this solutionis very simple with high security and high informationrate. Cheaters can only cheat via guessing with littleprobability.
