Abstract
The new quantum protocol of secret sharing between two subjects, which is based on the ping-pong protocol of quantum secure direct communication, is proposed. This protocol is based on scheme of transmission of the qubits by blocks, which is well known from publications. However, in contrast to this scheme in the proposed protocol the data transmission in a random way alternates with channel check on eavesdropping. Thereby the need for periodic storage of considerable number of qubits disappears. It will let to implement the procedure of secret sharing with assisting state-of-the-art technology of quantum information science. The proposed secret sharing protocol, which also uses the earlier developed by co-author the method of enhancement of the ping-pong protocols security, provides the high level of security to the outer malefactor’s eavesdropping attack. It is the advantage of this protocol over the appropriate classical (non-quantum) schemes.
