Universal share-based two-in-one multi-image secret sharing scheme by rotating random grids

EURASIP Journal on Information Security
Multi-image secret sharing (MSS) scheme for two decoding options by employing universal share is discussed in this manuscript. One decoding option is piling of shares to get a secret image preview and the other option needs computation of shares to get a

Lossless Recovery Scheme for Grayscale Visual Cryptography Based on Random Grids

Journal of Information Systems Engineering and Management
With the advancement of digitalization, the demand for grayscale image encryption has been increasing. Previous visual cryptography schemes for grayscale images have encountered issues such as information loss during recovery, poor recovery quality, and significant pixel expansion. This study introduces novel grayscale visual cryptography schemes based

A New Family of Soft Single Switched DC-DC Converters with Lossless Passive Snubber

Majlesi Journal of Electrical Engineering
In this paper, a novel lossless snubber is introduced that provides ZVS conditions for both On and Off instant of converter switches. On one hand, the energy of the snubber is optimally transmitted to the output so that no significant losses are imposed ...
