Abstract
A method and a device for remote acquisition of correlated pseudo-random numbers based on semi-trusted hardware. When applied to semi-trusted hardware, the method comprises: acquiring a random seed of a sender and a selected number of a receiver; generating a plurality of first correlated pseudo-random numbers and first commitment seeds according to the random seed and a predetermined category of the correlated pseudo-random number; generating a first commitment value and a first open value by a commitment mechanism according to the first correlated pseudo-random numbers and the first commitment seeds; generating a Merkle proof according to the first commitment value and the selected number; sending the first correlated pseudo-random numbers, the first commitment value, the first open value and the Merkle proof corresponding to the selected number to the receiver.
