Smart expansion of target key for more handlers to access multimedia counting-based secret sharing

The secret sharing scheme is a data security tool to provide safe reliability and robustness for multi-user authentication systems. This work focus on expanding counting-based secret sharing technique to generate more shares for more handlers’ services considering security as well as simple and fast computation. The research considers resolving some originally published imperfections in the share’s generation phase proposing new smart expansion models validated to be optimized practical and efficient. We proposed seven possible models to expand the number of participants for applicable share’s keys generated from the target key. The smart security randomness of the shares and target keys adjusted were all analyzed to select the best choice based on consistency randomness test. The study further used standard simulations applied on two different applicable multimedia target keys sizes of 16-bits and 64-bits showing attractive remarks pointing for further research improvements to continue. The improved smart system has been analyzed according to distortion security and capacity parameters showing attractive contributions.
