碩士 === 長庚大學 === 電機工程學系 === 102 === People changed in the habits of life gradually along with the advancement of technology and internet. The digital generation compared to the traditional living pattern is more convenient. An online lottery system needs to have perfect secure features so as to achieve the fairness. Functionality of the digital signature exactly can construct well for the working model. Due to the past signature schemes couldn't completely match the needs about scenarios of online lottery and offer consummate security and fairness. We propose an efficient t–out–of–n proxy oblivious signature scheme based on RSA cryptosystem. In response to the scenario of online lottery combines signatures of proxy and oblivious, and explain the analysis of security and argumentation. Furthermore, we applied in the smartphones equipped with the Android system. Compare to the traditional lottery game, it's more convenient for the users.
