Abstract

Based on the semi-quantum theory, we propose an easy-to-implement multi-party semi-quantum secret sharing scheme using Bell states, which reduces the construction cost of quantum secret sharing network and completes the multi-party secret sharing. The quantum Alice uses Bell states as the initial resource and has the abilities of performing Bell basis measurement and storing qubits, the participant Bobi has limited quantum capabilities. The secret sharing network based on semi-quantum theory completes the secret sharing between the secret distributor and multiple participants. Security analysis shows that the scheme can resist internal attacks and external entanglement attacks and is safe and feasible for current technologies.
