Undeniable threshold proxy signature scheme
2013 5th International Conference on Computer Science and Information Technology, 2013The 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, 2016Small 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
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 ...

Visual cryptography and threshold schemes
IEEE Potentials, 1999Visual 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, 2008A 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
2003We 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.

Features of Linguistic Threshold Schemes
2013In the discussion of strategic data splitting and sharing algorithms it has become necessary to embed linguistic algorithms of information splitting and data reconstruction in the solutions presented in this publication. The essence of this approach, representing an interdisciplinary topic straddling the border between the subjects of commercial ...

Threshold Undeniable RSA Signature Scheme
2001Undeniable signature has been extensively researched after Chaum and Antwerpen first proposed the concept of this special digital signature ten years ago. Up to now, however, almost all the existed schemes are based on discrete logarithm cryptosystems.

A Directed Threshold Signature Scheme
2017Directed signature is a solution of such problems when signed information is sensitive to message holder/signature receiver. Generally, in a directed signature, the signer is a single entity. But, when a sensitive message is signed by an organization and needs the approval of more than one entity, threshold signature scheme is a solution of this ...
