| Popis: | In this paper, we propose a threshold secret sharing scheme for secure communications even in the absence of eavesdropper channel state information. In the proposed scheme, the secret data is divided into N min parts by polynomial of degree T-1 and transmits to the target user through multiple spatial dimensions by beamforming. The divided secret data at the user can be reconstructed with a sufficient number (≥ T) of parts by using the Lagrange interpolating polynomial. The numerical results show that eavesdropping probability of the proposed scheme is better than those of the considered conventional schemes. |
