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.

Elliptic Threshold Secret Division Scheme
Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2009 The new aspect of proactive systems realization was developed based on elliptic curves arithmetic. Neural network model of secret division scheme at elliptic curve is introduced. Prolongation mechanism of the scheme was developed. Neural network model of

ID-based, Proxy, Threshold Signature Scheme [PDF]
International Journal of Electronics and Telecommunications, 2021 We propose the proxy threshold signature scheme with the application of elegant construction of verifiable delegating key in the ID-based infrastructure, and also with the bilinear pairings. The protocol satisfies the classical security requirements used

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

Combinatorial repairability for threshold schemes [PDF]
Designs, Codes and Cryptography, 2017 In this paper, we consider methods whereby a subset of players in a $(k,n)$-threshold scheme can "repair" another player's share in the event that their share has been lost or corrupted. This will take place without the participation of the dealer who set up the scheme.

Characterisations of Ideal Threshold Schemes [PDF]
Discrete Mathematics & Theoretical Computer Science, 2004 We characterise ideal threshold schemes from different approaches. Since the characteristic properties are independent to particular descriptions of threshold schemes all ideal threshold schemes can be examined by new points of view and new results on ideal threshold schemes can be discovered.

A Combinatorial Approach to Threshold Schemes [PDF]
SIAM Journal on Discrete Mathematics, 1988 We investigate the combinatorial properties of threshold schemes. Informally, a (t,w)-threshold scheme is a way of distributing partial information (shadows) to w participants, so that any t of them can easily calculate a key, but no subset of fewer than t participants can determine the key.

Brakke’s inequality for the thresholding scheme [PDF]
Calculus of Variations and Partial Differential Equations, 2020 AbstractWe continue our analysis of the thresholding scheme from the variational viewpoint and prove a conditional convergence result towards Brakke’s notion of mean curvature flow. Our proof is based on a localized version of the minimizing movements interpretation of Esedoğlu and the second author.

Secret Sharing, Zero Sum Sets, and Hamming Codes
Mathematics, 2020 A (t,n)-secret sharing scheme is a method of distribution of information among n participants such that any t>1 of them can reconstruct the secret but any t−1 cannot.

A Construction Method of (2, 3) Visual Cryptography Scheme
IEEE Access, 2020 Visual cryptography scheme (VCS) shares a binary secret image into multiple shadows, stacking qualified set of shadows will decode the secret image without computer resources.
