Embodiment Construction

[0011] A. Initialization phase:

[0012] 1. The lottery agent (LotteryAgent, hereinafter referred to as LA) announces the safe prime number p, and selects n lottery winning numbers a issued by LA i and the n pairs of data initially selected by LA (d i , d j ), n represents a natural number. where d i >a i , 1i , d j , (j≠i) is pairwise prime.

[0013] 2. LA calculates intermediate variables n is a natural number. Where (e, N) is the public key of LA, and LA calculates the intermediate variable

[0014] 3.LA Calculation Equations C = a 1 ( mod d 1 ) . ...

Abstract

The invention discloses a verifiable Internet lottery winning generation method, and the method comprises five stages: initialization stage, sales stage, lottery drawing stage, lottery conversion stage, and verification stage. The method achieves a series of properties, such as safety, correctness, anonymity, privacy, and convenience. Based on known safety knowledge, such as the Chinese remainder theorem, blind signature and verifiable random number, a protocol has calculation safety. Compared with a conventional Internet lottery, the lottery generated through the method is mainly characterized in guaranteeing that all participants have equal influence on the generation of winning numbers, and enabling the winning number to be verifiable.
