Secure verifiable secret short sharing scheme for multi-cloud storage

Abstract

In this paper, we propose a new approach to the construction of computationally secure secret sharing scheme based on the simultaneous use of the Residue Number System (RNS), as the symmetric encryption, and the perfect Asmuth-Bloom secret sharing scheme. We combine the useful features of Redundant RNS to design space efficient secret sharing scheme with enough level of security and to control of data integrity. This combination provides verifiability and achieves a high speed of data processing
