End-to-end encryption: State of the Technical and Policy Debate
Over the past decade, end-to-end encryption (E2EE) has been widely deployed in electronic messaging applications, including WhatsApp, Signal, Apple iMessage and others. This form of messaging ensures that information is encrypted from an end-user device (such as a phone) and remains encrypted until it reaches the destination. A key benefit of E2EE is that it protects messages from server-side hacking and mass surveillance. At the same time E2EE has created a vigorous pushback from the national security and law enforcement communities worldwide, as it significantly impedes investigative efforts. In this talk I will discuss the state of the E2EE messaging debate; the technical developments in this field; and the policy questions that remain.
