Quantum Secret Sharing Scheme

Based on an orthogonal set of product states of two three-state particles, a new quantum secret sharing scheme is proposed, which uses a novel distribution strategy so that continuous and independent measurements, rather than particle-wise coordinated ones, are performed. As a result, it is convenient and efficient to implement. The scheme is also secure against several common attacks and gets rid of partial-information leakage due to the revised coding method. Moreover, the quantitative analysis shows that the security can be further improved by using more product states from appropriate multiple sets.

Quantum Secret Sharing Scheme

A recent paper proposed a semi-quantum secret sharing (SQSS) scheme based on Bell states [A. Yin et al., Mod. Phys. Lett. B. https://doi.org/10.1142/S0217984917501500 ]. This protocol was presumed that only the sender has the quantum power and all participants perform classical operations. However, we find this protocol is not that secure as it is expected. We can utilize the intercept-resend method to attack this scheme. Then, we give an improvement strategy based on semi-quantum key distribution, which ensures that the new scheme resists the attack we have proposed.

Quantum Secret Sharing Scheme

Semi-quantum secret sharing (SQSS) can transmit secret messages. Most existing SQSS protocols can only use one or two specific entangled states to share unspecific or specific classical message. In this paper, we propose a novel SQSS protocol using N different unspecific two-particle entangled state [Formula: see text], [Formula: see text] to share unspecific message, in which quantum Alice can transmit classical messages with classical Bob and Charlie. In addition, we have proved that the protocol can strongly resist some forms of eavesdropping.
