Lattice-based threshold-changeability for standard CRT secret-sharing schemes
We consider the problem of increasing the threshold parameter of a secret-sharing scheme after the setup (share distribution) phase, without further communication between the dealer and the shareholders. Previous solutions to this problem require one to start off with a non-standard scheme designed specifically for this purpose, or to have secure channels between shareholders. In contrast, we s...
متن کاملDealer-Free Threshold Changeability in Secret Sharing Schemes
This paper proposes a dealer-free threshold changeable construction for secret sharing schemes. In practice, the adversary’s ability might be enhanced over time, for instance by compromising more players. This problem can be resolved only by increasing the threshold. In the literature, there exist some techniques to address this issue. These solutions either have a large storage requirement or ...
متن کاملCRT Based Threshold Multi Secret Sharing Scheme
This paper presents a novel secret sharing system that is based on Chinese remainder theorem. This scheme deals with a concept of multiple secrets to be shared to different groups, such that each group receives shares of secret intended for it. The sharing is a threshold scheme, that is more than a fixed number of members from any particular group, will be able to reconstruct the secret and any...
متن کاملOn the design and security of a lattice-based threshold secret sharing scheme
In this paper, we introduce a method of threshold secret sharing scheme (TSSS) in which secret reconstruction is based on Babai's nearest plane algorithm. In order to supply secure public channels for transmitting shares to parties, we need to ensure that there are no quantum threats to these channels. A solution to this problem can be utilization of lattice-based cryptosystems for these channe...
متن کاملRepairable Threshold Secret Sharing Schemes
In this paper, we propose a class of new threshold secret sharing schemes with repairing function between shares. Specifically, each share, when it is broken or lost, can be repaired by some others without the help of the dealer. Further, a construction of such repairable threshold secret sharing schemes is designed by applying linearized polynomials and regenerating codes in distributed storag...
