Geometric Threshold Schemes

1990
This paper gives constructions of infinite classes of 2, 3 and 4-threshold schemes based on finite incidence structures such as generalised quadrangles and projective planes.

Certificateless Threshold Signature Schemes

2005
We 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.

Analysis of fuzzy thresholding schemes

Pattern Recognition, 2000
Abstract Fuzzy thresholding schemes preserve the structural details embedded in the original gray distribution. In this paper, various fuzzy thresholding schemes are analysed in detail. Thresholding scheme based on fuzzy clustering has been extended to a possibilistic framework.

Undeniable threshold proxy signature scheme

2013 5th International Conference on Computer Science and Information Technology, 2013
The threshold proxy signature scheme allows the original signer to delegate a signature authority to the proxy group member to cooperatively sign message on behalf of an original signer. In this paper, we also propose a new scheme which includes the features and benefits of the RSA scheme which is a popular security technique.

Distributed Iterative Threshold Control Scheme

IEEE Communications Letters, 2016
Small cell is one of the key technologies in modern wireless communications, extending cell coverage and providing capacity increment. However, challenges still exist in realizing and optimizing the small cell networks. In this letter, we propose a distributed iterative threshold control scheme with minimal increase in hardware complexity to improve ...

Threshold proxy signature schemes

1998
Delegation 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 ...

Visual cryptography and threshold schemes

IEEE Potentials, 1999
Visual cryptography is a secret sharing scheme that uses the human visual system to perform computations. In this article, we present some background to traditional secret-sharing schemes, then explain visual schemes, describing some of the basic construction techniques used.

A Multisecret Sharing Threshold Scheme

2008 Ninth ACIS International Conference on Software Engineering, Artificial Intelligence, Networking, and Parallel/Distributed Computing, 2008
A threshold sharing scheme is a system that protects a secret (key) among a group of participants in such a way that it can only be reconstructed from pooled information held by some certain number of these authorized participants. In this paper we extend this problem to one where there are multiple secrets which participants need reconstruct using the

A Threshold GQ Signature Scheme

2003
We proposed the first threshold GQ signature scheme. The scheme is unforgeable and robust against any adaptive adversary if the base GQ signature scheme is unforgeable under the chosen message attack and computing the discrete logarithm modulo a safe prime is hard. Furthermore, our scheme can achieve optimal resilience by some modification.
