Usable everlasting encryption using the pornography infrastructure

Abstract

—Nine years before Snapchat and its ephemeral messages, Aumann, Ding, and Rabin introduced the idea of everlasting security: an encryption that could not be decrypted after a certain date, no matter the adversary’s computing power. Their method is efficient but not adapted to real-life constraints and cannot effectively be used today. In this paper we look at potential entropy sources available today, and propose a new solution that makes use of the already existing communications from pornography distribution networks, and look at its social implications. The method pro- posed has multiple advantages stemming from the fact that pornography is shameful in most societies, and it is usable off- the-shelf by individuals with limited technical skills, although it still requires some effort.
