Claim 0:
1. A method for remote acquisition of correlated pseudo-random numbers based on semi-trusted hardware, which is applied to semi-trusted hardware, comprising:
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; and
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, so that the receiver verifies the first commitment value according to a Merkle root and the Merkle proof sent by the sender and verifies the correlated pseudo-random numbers corresponding to the selected number according to the verified first commitment value and the first open value.
