Threshold quantum cryptography

Physical Review A, 2005
We present the concept of threshold collaborative unitary transformation or threshold quantum cryptography, which is a kind of quantum version of threshold cryptography. Threshold quantum cryptography states that classical shared secrets are distributed to several parties and a subset of them, whose number is greater than a threshold, collaborates to ...

Contrast Optimal Threshold Visual Cryptography Schemes

SIAM Journal on Discrete Mathematics, 2003
The Threshold Visual Cryptography Schemes (VCS) were introduced by \textit{M. Naor} and \textit{A. Shamir} [Lect. Notes Comput. Sci. 950, 1--12 (1995; Zbl 0878.94048)] and have been widely studied since then. A \((k,n)\)-threshold VCS is a method of sharing a secret (black and white) image among a set of \(n\) participants, giving to each of them a ...

Threshold Cryptography

European Transactions on Telecommunications, 1994
AbstractIn the traditional scenario in cryptography there is one sender, one receiver and an active or passive eavesdropper who is an opponent. Large bank transactions require two people to sign, implying two senders. So the power to generate a valid transaction is shared.

Optimal Colored Threshold Visual Cryptography Schemes

Designs, Codes and Cryptography, 2005
Visual cryptography schemes allow a dealer to divide a secret image into \(n\) shares which can then be distributed to the participants. Part of the participants receive special shares, with special properties which allow them to recover the original image from the shares they have. Such shares are considered to be all in the same set, and the sets are
