Abstract

Verifiable secret sharing (VSS) is a fundamental tool of threshold cryptography and distributed computing. A number of VSS schemes for sharing a secret that is an element of a finite field, either on threshold access structures or on general access structures have been available. In this paper, we study the verifiably sharing of a random element of a bilinear group on vector space access structures. We propose such two information-theoretical secure schemes: a basic scheme and a modified one with improved efficiency. The basic one is more general for applications while the modified one has a smaller computational cost compared with the basic one. The computational cost as well as the security analysis for the proposed schemes are presented.
