DOI: 10.1007/s11042-019-08524-x
Abstract: Boolean-operation-based secret image sharing (BSIS), which aims to encode a secret image into some shared images and discloses the original secret image later, has drawn more and more attention in academia. Since Chen and Wu… read more here.

DOI: 10.1007/s11277-017-5187-y
Abstract: A multi-secret sharing scheme tries to share multiple secrets among a group of players in such a way that co-operation of pre-specified subsets of them, called access structures, can reconstruct the secrets. Existing methods allow… read more here.

DOI: 10.1109/jsac.2022.3142375
Abstract: We study the equivalence between non-perfect secret sharing (NSS) and symmetric private information retrieval (SPIR) with arbitrary response and collusion patterns. NSS and SPIR are defined with an access structure, which corresponds to the authorized/forbidden… read more here.

DOI: 10.1109/tit.2021.3123102
Abstract: Multipartite secret sharing schemes are those having a multipartite access structure, in which the set of participants is divided into several parts and all participants in the same part play an equivalent role. Secret sharing… read more here.

DOI: 10.1109/tit.2023.3322601
Abstract: Secret sharing is a method to distribute a secret amongst participants, such that only some predefined coalitions, called qualified sets can recover the secret. The set of the qualified subsets is called the access structure,… read more here.
