Abstract

A method in which a secret is distributed among the users and a predefined number of users collaborate to reconstruct the secret is known as a secret sharing scheme. In this article, we have proposed a conjunctive hierarchical multi-secret sharing scheme using elliptic curves and bilinear pairings. The motivation for utilizing bilinear pairing of elliptic curves is to provide a similar level of security as in many existing schemes while employing a smaller key size. The proposed scheme is efficient and verifiable. The computational cost of the scheme is determined. We have also given an explicit example of the proposed scheme.
