Abstract:
The present invention provides a method which includes: receiving, by a first node in a first period of time, n encrypted random parameters sent by n second nodes in a system, where n is a positive integer; receiving, by the first node in a second period of time, n mapping relationships and n keys that are sent by the n second nodes, where each mapping relationship is a one-to-one mapping relationship between an encrypted random parameter and a key; and decrypting, by the first node in a third period of time, the n encrypted random parameters by using the n mapping relationships and the n keys, to obtain a target random parameter set, and generating target winning numbers by using the target random parameter set, so that each node can generate the winning numbers and verify impartiality of the winning numbers, thereby increasing randomness of a random parameter.

Claim (Index 1):
A method for generating winning numbers, wherein the method comprises:\n receiving, by a first node in a first period of time, n encrypted random parameters sent by n second nodes in a system, wherein n is a positive integer; receiving, by the first node in a second period of time, n mapping relationships and n keys that are sent by the n second nodes, wherein each mapping relationship is a one-to-one mapping relationship between an encrypted random parameter and a key; and decrypting, by the first node in a third period of time, the n encrypted random parameters by using the n mapping relationships and the n keys, to obtain a target random parameter set, and generating target winning numbers by using the target random parameter set, wherein the first period of time, the second period of time, and the third period of time are chronologically arranged in ascending order.
