Instant-open type of lottery issuing scheme based on WAP

Based on analyzing the general properties of instant-open type of lottery,WAP security model and WPKI,an instant-open type of lottery issuing scheme based on WAP is propsed,which realizes a cellphone instant-open type of lottery business by utilizing WAP.In this scheme,lottery issuers set the wning numbers and wbus in advance of issuing the lottery,and set the wning numbers and content of lotteries based on the difficulty of solving the elliptic curve discrete logarithms problem.At the same time,in this scheme the public key cryptography uses elliptic curve cryptography(ECC),the information of wning could be verified by using Hash function.At last,it realizes encashing the wbus flexibly by applying WAP security vulnerability.
