A Fair (t,n) Threshold Secret Sharing Scheme

The cloud service provider offers various storage services for mass data. However, for safety and recovery concern, the provider distributes the components of the data file on different servers. Therefore it is important to design appropriate secret sharing scheme. In this paper, we hide the real secret value in a sequence of pseudo secrets in order to decrease the probability of the cheater achieving a successful guess. We also use the multiple secret sharing techniques to realize efficient distribution and reconstruction, which reduce the storage burden of the user. Furthermore, we also make some analyses of our scheme and do some comparisons. Our scheme provides better secret reconstruction and helps improve the fairness of the existing scheme.
