Abstract

Abstract: A new E-lottery scheme is proposed based on verifiable random function and multi-level hash chain.This scheme satisfies various requirements of electronic lottery and no trusted third-party is needed in the whole process.The purchaser can verify whether the winning number is forgery.This scheme has the property of anonymity，non-forgeability，non-repeatability and public verifiability.Compared with other schemes，this scheme is more efficient.

Key words: electronic lottery, verifiable random function, multi-level hash chain, interpolation polynomial

摘要： 基于可验证随机函数且结合分层hash链结构设计了一种新的电子彩票方案。该方案能满足电子彩票的多种要求，在整个过程中不需要可信任第三方参与，并且Purchaser可轻松验证最终中奖数字是否伪造，具有匿名性、不可伪造性、不可重复性、公开验证性等安全特点。与其他方案进行比较，表明该方案的效率更高。
