摘　　要：随着电子商务的日益成熟,电子彩票也将是人们生活中不可缺少的商务活动之一。在对传统的彩票随机数产生系统研究基础上,设计了一种基于USBKey设备的电子彩票随机数产生系统,并分析了该系统的安全性。与传统的彩票随机数产生系统相比,该系统发行的电子彩票由发行中心产生的随机数、公证机构的签名,以及全体公众的共同购买行为所决定,具有更安全、更公正、更公平的优点。With the increasing popularity of e-commerce, electronic lottery becomes one of the indispensable businesses on the Internet. Based on the study of traditional lottery ticket random number generation scheme, an electronic lottery random number generation scheme based on USBkey is proposed and designed, and its safety is analyzed. Compared with the traditional lottery ticket scheme, the electronic lottery ticket released by this proposed scheme is determined by the random number of lottery center, the signature of notary office, and the behaviors of public purchase, so this scheme is more safe, more impartial and fairer.
