Abstract:

The process of multiple secret sharing scheme construction is the method of distributing arbitrary linked secrets among participants. Research in this area aims at reduction of the algorithmic complexity and at the same time, the increasing of their speed. In this paper, a multiple secret sharing scheme based on use of residue number system RNS and Toeplitz matrix is proposed. Tests show high performance of secret sharing and recovery schemes when compared to some frequently used secret sharing models.
The paper is organized as follows: after introduction in section 1, section 2 gives methods and algorithms used. Work in section 3 concern secret sharing scheme using the Toeplitz matrix. In section 4 we have model and analysis of the computational complexity. Paper concludes in section 5.
