An Efficient Verifiable Threshold Multi-Secret Sharing Scheme With Different Stages
IEEE Access, 2019 Secret sharing is one of the most important cryptographic primitives used for data outsourcing. The threshold-based secret sharing scheme is one of the well-known secret sharing schemes in cryptography.

Improvement of lightweight threshold group signature scheme
网络与信息安全学报, 2020 In order to improve the security and efficiency of threshold group signature in 5G environment,a new scheme was proposed.The core idea was to introduce message token and dynamic identity to improve the freshness of authentication information and increase

Dynamic Multi-threshold Metering Schemes [PDF]
, 2001 A metering scheme is a protocol in which an audit agency is able to measure the interaction between clients and servers on the web during a certain number of time frames. Naor and Pinkas [7] considered metering schemes in which any server is able to construct a proof to be sent to the audit agency if and only if it has been visited by at least a number,

Verifiable (n,n) Threshold Quantum Secret Sharing Scheme [PDF]
Jisuanji gongcheng, 2017 This paper constructs a class of verifiable secret sharing scheme based on Chinese Remainder Theorem and Bell states.In the distribution phase,Alice distributes the shares to the participants through the quantum secure channel.In the recovery phase,Alice

Threshold Schemes with Disenrollment [PDF]
Proceedings. IEEE International Symposium on Information Theory, 2005 When a shadow of a threshold scheme is publicized, new shadows have to be reconstructed and redistributed in order to maintain the same level of security. In this paper we consider threshold schemes with disenrollment capabilities where the new shadows can be created by broadcasts through a public channel. We establish a lower bound on the size of each

A proposal for highly tunable optical parametric oscillation in silicon micro-resonators [PDF]
, 2008 We propose a novel scheme for continuous-wave pumped optical parametric oscillation (OPO) inside silicon micro-resonators. The proposed scheme not only requires a relative low lasing threshold, but also exhibits extremely broad tunability extending from ...

Multisecret Threshold Schemes [PDF]
, 2007 A threshold 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 the joint information held by some predetermined number of these participants. In this paper we extend this problem to one where there is more than one secret that participants can reconstruct using the ...
