Threshold Undeniable RSA Signature Scheme

, 2001
Undeniable 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 novel nonrepudiable threshold multi-proxy multi-signature scheme with shared verification

Computers and Electrical Engineering, 2009
Tzeng et al. proposed a new threshold multi-proxy multi-signature scheme with threshold verification. In their scheme, a subset of original signers authenticates a designated proxy group to sign on behalf of the original group.

A Novel Threshold Changeable Secret Image Sharing Scheme

Symmetry, 2021
In secret image sharing, the image is divided into several stego images, which are managed by corresponding participants. The secret image can be recovered only when the number of authorized participants is no less than the threshold.

Adaptive threshold control scheme for packet acquisition

IEEE Transactions on Communications, 1998
An adaptive threshold control scheme for packet acquisition is described. The threshold control is done adaptively by setting the threshold proportional to the maximum likelihood estimate of the noise ...

Analysis of fuzzy thresholding schemes

Pattern Recognition, 2000
Abstract Fuzzy thresholding schemes preserve the structural details embedded in the original gray distribution. In this paper, various fuzzy thresholding schemes are analysed in detail. Thresholding scheme based on fuzzy clustering has been extended to a possibilistic framework.

A note on the randomness in dynamic threshold schemes

Journal of Computer Security, 1999
In dynamic threshold schemes the dealer is able (after a preprocessing stage) to allow sets of participants of a given cardinality to reconstruct different secrets (in different time instants) by sending them the same broadcast message. In this paper we provide a tight lower bound on the number of random bits needed by the dealer to set up a dynamic ...
