Broadcasting cryptosystem in computer networks using geometric properties of lines

Abstract

In 1997, Wu and Wu proposed an improvement of the Chang-Wu broadcasting cryptosystem using geometric properties of lines. The Wu-Wu scheme gave a better performance and required fewer public parameters than the Chang-Wu scheme. In this paper the authors propose an improvement to the Wu-Wu scheme using geometric properties of line. This improvement reduces the computation and significantly decreases the parameters required as compared to the Wu-Wu scheme.
