- Abstract
- 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 Nmin 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 (?돟 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.
