Abstract

We investigate a number of issues related to the use of multiple trust authorities in the type of identifier based cryptography enabled by the Weil and Tate pairings. An example of such a system is the Boneh and Franklin encryption scheme. We examine how to create an efficient hierarchy of multiple trust authorities and then go on to examine some application areas of pairing based cryptography.
