Abstract
A processor generates a first seed, wherein the first seed is a random number. The processor generates, a digital signature of the first seed. An interface communicates digital signature of the first seed to a first remote entity. The interface receives a digital signature of a second seed. After communicating the digital signature of the first seed to the first remote entity, the interface receives the second seed from the first remote entity. After receiving the digital signature of the second seed, the interface communicates the first seed to the first remote entity. The processor determines, using the digital signature of the second seed and the second seed, whether the second seed is valid. Upon a determination that the second seed is valid, the processor combines the first seed and the second seed to form a drawing seed. The processor generates a first draw result using the drawing seed and a drawing algorithm. The interface receives a second draw result from the first remote entity. The processor compares the first draw result and the second draw result. The processor communicates the draw results upon a determination that the first draw result and the second draw result are…
