Problems solved by technology

In reality, there are certain difficulties in the design of the delay function, mainly because there are some difficulties in predicting the attacker's computing power, which makes it difficult to control how long the delay function will be delayed.
If the delay time is short, it may lose its effect; if the delay time is long, it may affect the practicability of the release

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.

Description

technical field [0001] The invention relates to the field of information systems, in particular to a verifiable Internet lottery winning generation method. Background technique [0002] According to the China Lottery Industry Research Analysis and Market Prospect Forecast Report released by China Market Research Network, the total sales of lottery tickets nationwide in 2014 reached 380.278 billion yuan, an increase of 73.053 billion yuan over 2013, an increase of 23.6%. In 2014, the per capita disposable income of Chinese residents was 20,167 yuan, an increase of 10.1% over 2013. According to the Asian 366.2 yuan, in 2014, my country's lottery sales were 382.3 billion yuan, a year-on-year increase of 32%, and the per capita ticket purchase was 274 yuan. At present, China's lottery industry is in a period of rapid development. The multicultural population, long history and tradition, and sustained and rapid economic growth provide a huge development space for the lottery mar...
