Abstract

In 2009, a non-iterative privacy preservation for online lotteries is proposed in IET Information Security. In this paper, we analyze the security flaw of Lee-Chan-Chang’s scheme that can not provide the public verification. With Lagrange interpolating formula over , the method of verifiable random number is introduced, which makes each purchaser involved equally in the generation of winning result. Trusted third party is no longer necessary, which eliminate the fairness bottleneck..
