Increasing Efficiency of International Key Escrow in Mutually Mistrusting Domains

This paper is concerned with key escrow protocols for use in international communications environments, where communication domains do not necessarily trust one another. It is concerned particularly with systems where users place their trust collectively with groups of trusted third parties. We consider two different protocols, discuss and improve their efficiency and generalise the type of key splitting.
