Abstract:

Based on Linear error-correcting codes, a cheating-detectable quantum secret sharing scheme with $\varepsilon $ security is proposed. In this scheme, the secret is uniquely determined by the column index of the orthogonal array and two elements in a row. The column index of the orthogonal array is recovered in the classical channel through an asymmetric bivariate polynomial. The two elements in a row are partially recovered in the quantum channel based on the linear error correction code. This scheme not only has the function of identifying and authenticating cheaters, but also realizes double encryption of secrets. Security analysis shows that the protocol is capable of resisting interception retransmission attacks and entanglement measurement attacks externally.

Key words: quantum secret sharing, orthogonal array, linear error-correcting codes, asymmetric bivariate polynomials
