Abstract

In this paper we present the first implementation of high-speed filesystem encryption with a slow JAVA card. Using new "Remotely Keyed Protocols" designed by Lucks and Weis we can use the highly tamper-resistant JAVA ring, and even restrict ourselves to a version of the ring without built-in encryption. We have implemented this protocols on the ring and give a first performance comparision.
