Abstract

In this paper we propose a novel solution to the problem of providing trusted third party services, such as the management of cryptographic keys for end-to-end encryption, in a way that meets legal requirements for warranted interception. Also included is a discussion of what might be a reasonable set of requirements for international provision of such services, as well as some analysis of the cryptographic properties of the architecture and how it might operate in practice.
