Abstract

The invention discloses a quantum secret sharing method based on a Bell state. The quantum secret sharing method is characterized by comprising a secret distributor and n participants, the secret distributor distributes a random secret to the n participants, wherein each participant obtains a sub-secret, when the n participants accumulate all sub-secrets, the originally shared secret can be restored, and any information of the shared secret cannot be obtained less than n participants. By adoption of the quantum secret sharing method disclosed by the invention, the problems of participant fraud, low security, complexity and efficiency of channels in the existing quantum secret sharing process are solved, the quantum and classical resources can be saved, the operation complexity is reduced, and higher quantum efficiency is ensured.

Description

technical field

[0001] The invention belongs to the field of secure multi-party calculation and modern cryptography application, in particular to a Bell state-based quantum secret sharing method. Background technique

[0002] Secret sharing plays a fundamental role in secure multi-party computing and modern cryptography, and is an important atomic protocol in secure multi-party computing. A secret sharing scheme usually consists of two algorithms: a secret share distribution algorithm and a secret recovery algorithm. In the secret share distribution algorithm, the distributor divides the secret into several shares and distributes them among a group of participants, so that each participant gets one of the secret shares. In the secret recovery algorithm, only some specific subset of participants (authorized subset) can recover the secret, and other non-authorized subsets cannot recover the secret, or even get any useful information about the secret.
