Abstract: In 2002, Hwang et al. proposed a broadcasting cryptosystem in computer networks using the geometric properties of lines. Their scheme consumes less computing time and requires fewer public parameters than Wu and Wu|s scheme. In this paper, the authors will propose a simple eXclusive-OR operation to live up to the requirements a good broadcasting cryptosystem should, and it even consumes less computing time and requires fewer public parameters than the Hwang et al. scheme.
Keywords: broadcasting cryptosystems; network security; networking; encrypted messages.
