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 ...

A Secure Boolean-based Multi-Secret Image Sharing Scheme
, 2014 Multiple secret images Boolean XORAn (n, n) multi-secret image sharing scheme shares n secret images among n shared images. In this type of schemes, n shared images can be used to recover all n secret images, but the loss of any shared image prevents the

A Practical (t,n) Multi-secret Sharing Scheme [PDF]
, 2012 [[abstract]]Based on the systematic block codes, we propose a (t,n) multi-secret sharing scheme. Compared with the previous works, our schemc has the advantages of smaller communication overhead, easy generator matrix construction and nondisclosure of ...

Monolithically 3D‐Printed Spectral‐Spatial Meta‐Authenticators
Advanced Materials, EarlyView.A single height map printed in a low‐index resin by two‐photon lithography encodes multiple visible wavelengths in one metasurface without any polarization optics. A fabrication‐aware optimization folds the printable height levels into the design, so the device is printed as optimized.

Advanced Materials Technologies, EarlyView.This review summarizes moisture‐adaptive strategies that enable triboelectric nanogenerators (TENGs) to operate across diverse moisture conditions. It examines moisture‐management methods, including exclusion, directional transport, removal, and utilization, with charge‐regulation approaches based on interfacial, dielectric, and structural engineering.
