In order to ensure the information security, most of the important information including the
data of advanced metering infrastructure (AMI) in the energy internet is currently transmitted …

Threshold signatures protect the signing key by sharing it among a group of signers so that
an adversary must corrupt a threshold number of signers to be able to forge signatures …

Secret sharing has a number of practical applications in network-based scenarios, such as
key transfer protocols, attribute-based encryption and secure multiparty computation …

Hierarchical secret sharing is an important key management technique since it is specially
customized for hierarchical organizations with different departments allocated with different …

Secret-sharing allows splitting a piece of secret information among a group of shareholders,
so that it takes a large enough subset of them to recover it. In weighted secret-sharing, each …

Multipartite secret sharing schemes are those having a multipartite access structure, in
