The notion of families of ideal threshold schemes (ITS) is introduced, their properties and applications are investigated. We consider secret sharing schemes whose parameters can be adjusted. Our model is a threshold scheme family (TSF) whose threshold scheme parameters can be modified dynamically. Some applications of this model includes schemes which

Certificateless Threshold Signature Schemes
2005We analyze the relationship and subtle difference between the notion of certificateless public key cryptography (CL-PKC) and identity-based schemes without a trusted private key generator (PKG), then propose a certificateless threshold signature scheme based on bilinear pairings.

Threshold signature schemes for ElGamal variants
Computer Standards & Interfaces, 2011In this paper we present a generic construction of threshold ElGamal signature schemes. We classify ElGamal variants by two types according to ways of generating signatures. Then we develop the generic mechanism to convert a group of ElGamal variants into their threshold versions and prove unforgeability of constructed schemes.

Threshold Schemes from Isogeny Assumptions
2020We initiate the study of threshold schemes based on the Hard Homogeneous Spaces (HHS) framework of Couveignes. Quantum-resistant HHS based on supersingular isogeny graphs have recently become usable thanks to the record class group precomputation performed for the signature scheme CSI-FiSh.

A Threshold Multi-secret Sharing Scheme
2008 IEEE International Conference on Networking, Sensing and Control, 2008This paper proposes a threshold multi-secret sharing scheme. In such a scheme, many secrets are shared in such a way that all secrets can be reconstructed independently without refreshing the shares. Every share is of the same size as that of any single shared secret in the proposed scheme.

Threshold proxy signature schemes
1998Delegation of rights is a common practice in the real world. Proxy signature schemes have been invented to delegate signing capability efficiently and transparently. In this paper, we present a new nonrepudiable proxy signature scheme. Nonrepudiation means the signature signers, both original and proxy signers, cannot falsely deny later that he ...

A Multi-attribute Hierarchical Threshold Scheme
2011 International Conference on Internet of Things and 4th International Conference on Cyber, Physical and Social Computing, 2011A hierarchical threshold scheme is a scheme to solve the secret sharing with a hierarchical access structure where participants are partitioned into different levels. In the past hierarchical threshold scheme participants are partitioned based on a single attribute.

Breaking and Building of Threshold Signcryption Schemes
2010Signcryption is a cryptographic primitive that fulfills both the functions of digital signature and public key encryption in a single step, at a cost significantly lower than that is required by the traditional signature-then-encrypt approach. Threshold involved with signcryption is used where the sender or receiver side has a group of members ...
