Secret sharing scheme plays a crucial role in distributed cryptosystems. Due to its extensive use in numerous applications, an important goal in this area is to minimize trust among the participants. To remove this bottleneck, robust secret sharing, which allows the correct secret to be recovered even when some of the shares presented during an attempted reconstruction are incorrect, can be an efficient tool. However, as unconditional security demands honest majority and share size to be at least equal to the size of the secret, the need for computational security of such schemes has been felt over the years, specially in case of multi-secret sharing schemes. In this paper, we provide a notion of computationally robust multi-secret sharing scheme for general access structure. We also propose a robust multi-secret sharing scheme for general access structure and prove its computational security under the proposed notation. © Springer India 2015.
