Tamper-proof secret image-sharing scheme for identifying cheated secret keys and shared images [PDF]
, 2013 [[abstract]]A (t,n) secret image-sharing scheme shares a secret image to n participants, and the t users recover the image. During the recovery procedure of a conventional secret image-sharing scheme, cheaters may use counterfeit secret keys or modified ...

Periodical Multi-secret Threshold Cryptosystems [PDF]
, 1999 A periodical multi-secret threshold cryptosystem enables a sender to encrypt a message by using a cyclical sequence of keys which are shared by n parties and periodically updated. The same keys appear in the same order in each cycle, and thus any subset of t+1 parties can decrypt the message only in the periodical time-frames, while no subset of t ...

Conjunctive Hierarchical Multi-Secret Sharing Scheme using Elliptic Curves
Indian Journal of Pure and Applied Mathematics, 2023 In the present paper, the authors provide a conjunctive hierarchical multi-secret sharing scheme using elliptic curves and bilinear pairings. The scheme distributes several secrets among users grouped in hierarchical levels, where only authorized subsets of users from each level can collaborate to reconstruct the secrets.

An ideal multi-secret sharing scheme based on minimal privileged coalitions [PDF]
, 2012 How to construct an ideal multi-secret sharing scheme for general access structures is difficult. In this paper, we solve an open problem proposed by Spiez et al.recently [Finite Fields and Their Application, 2011(17) 329-342], namely to design an ...

Updating the parameters of a threshold scheme by minimal broadcast [PDF]
, 2005 Threshold schemes allow secret data to be protected among a set of participants in such a way that only a prespecified threshold of participants can reconstruct the secret from private information (shares) distributed to them on a system setup using ...
