Semi-quantum secret sharing method with limited quantum resources

Abstract

The invention discloses a quantum resource limited semi-quantum secret sharing method. Semi-quantum secret sharing usually includes that a quantum side Alice divides a secret into two parts and sendsthem to quantum resource limited Bob and Charlie respectively, and only when the Bob and the Charlie cooperate, the complete secret be recovered. At present, the typical semi-quantum secret sharing method guarantees the security, but requires the semi-quantum sides Bob and Charlie to perform quantum measurement operations. The measurement device may be unsafe, which increases the hidden danger ofsecret sharing. The present invention enables the resource limited Bob and Charlie to perform secret sharing without a quantum measurement device, and the quantum side Alice does not require quantum memory. In this way, the present invention can greatly reduce the quantum resources required by the three participants, thereby saving the communication cost.

Description

technical field [0001] The invention relates to a semi-quantum secret sharing method, which belongs to the field of quantum cryptography. Background technique [0002] With the development of science and technology, information security on the network has become an indispensable part of today's society, and people are paying more and more attention to the protection of personal privacy, but now there are various eavesdropping behaviors, which pose a huge threat to people's privacy . Although there are many classic ways to resist eavesdropping, it is impossible to prevent and discover eavesdropping in all cases. Quantum cryptography combines the characteristics of quantum mechanics and can be theoretically absolutely secure. As a branch of quantum cryptography, quantum secret sharing plays an important role in distributing keys, and semi-quantum secret sharing with limited quantum resources simplifies the quantum capabilities required by participants, thereby reducing commu...
