Classification: CPC G  H | IPC G  H

Claim 9:
10. A device for remote acquisition of correlated pseudo-random numbers based on semi-trusted hardware, which is applied to the receiver, with the method according to claim 9, comprising:
a receiving module configured to receive an encrypted random seed sent by a sender;
a fourth sending module configured to send the encrypted random seed and a selected number to this capable of obtaining the random seed of the sender and the selected number of a receiver; generate a plurality of first correlated pseudo-random numbers and first commitment seeds according to the random seed and a predetermined category of correlated pseudo-random numbers; generate 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; generate a Merkle proof according to the first commitment value and the selected number; send 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; and
a second verification module configured to verify the first commitment value according to a Merkle root and the Merkle proof sent by the sender, and verify the correlated pseudo-random numbers corresponding to the selected number according to the verified first commitment value and the first open value.
