Multiparty Quantum Secret Sharing of Key Using Practical Faint Laser Pulses
Zhanjun Zhang, Man Zhong-Xiao · Chinese Physics Letters · 2005
Based on a bidirectional quantum key distribution protocol [Phys. Rev. A 70 (2004) 012311], we propose a ( m −1, m −1)-threshold scheme of m ( m ⩾ 3)-party quantum secret sharing of key by using practical faint laser pulses. In our scheme, if all the m −1 sharers collaborate, they can obtain the joint secret key from the message sender. Our scheme is more feasible according to the present-day technology.
