Title:
METHOD AND APPARATUS FOR GENERATING WINNING NUMBERS
Document Type and Number:
WIPO Patent Application WO/2017/084080
Kind Code:
A1
Abstract:
Provided are a method and apparatus for generating winning numbers. The method comprises: a first node receiving, within a first time period, n encrypted random parameters sent by n second nodes in a system, wherein n is a positive integer; the first node, within a second time period, receiving n mapping relationships and n keys sent by the n second nodes, wherein each of the mapping relationships is a one-to-one mapping relationship between an encrypted random parameter and a key; and the first node utilizing the n mapping relationships and the n keys to decrypt the n encrypted random parameters within a third time period to obtain a target random parameter set, and utilizing the target random parameter set to generate target winning numbers. Each node can generate winning numbers and verify the fairness of the winning numbers, and the randomness of a random parameter is increased.
