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。
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-repeatabili-ty and public verifiability.Compared with other schemes,this scheme is more efficient.
