A Dynamic(t,n)Threshold Quantum Secret Sharing Scheme with Cheating Identification
Based on homogeneous linear feedback shift register(LFSR)sequences and d-dimensional single quantum states,this paper proposed a dynamical(t,n)threshold quantum secret sharing scheme with cheating identification.In this scheme,a trusted dealer determined the shared secret and distributed shared to the participants,and the participants recovered the secret by performing the corresponding unitary operation on the transmitted particles.In the secret reconstruction phase,by performing quantum state digital signatures,not only the existence of cheating behavior could be detected,but also the specific cheater could be identified and removed,and finally the participants could verify the correctness of the recovered secret.The scheme allowed dynamic updating of participants without changing the shares of old participants and without the help of other participants.Security analysis shows that the scheme is resistant to common external and internal attacks.
