End-to-End Encryption and “Going Dark”

Schneier on Security

July 23, 2026 at 11:03 AM

Overview

A new paper updates the debate on end-to-end encryption (E2EE), marking what the authors call 'Round 3' of the Going Dark Debate. This discussion centers on the tension between privacy and law enforcement, as governments globally push for laws that restrict E2EE to enable access for security purposes. The paper outlines the history of encryption debates, starting with the Crypto Wars of the 1990s, followed by a phase where lawful access was feasible through cloud services. Currently, the rise of E2EE means that messages are secure from third-party access, complicating law enforcement efforts. The implications of this research are significant, as it challenges policymakers to balance privacy rights with national security needs, affecting users, tech companies, and governments alike.

Original Article Summary

New paper: “Encryption and Globalization 15 Years Later: End-to-End Encryption and the Third Round of the ‘Going Dark’ Debate“: Abstract: This Article updates and expands on 2012 research on encryption and globalization, analyzing what the authors call “Round 3” of the Going Dark Debate: the current controversies over end-to-end encryption (E2EE). Governments around the world have proposed, and in some cases enacted, laws limiting E2EE for law enforcement and national security purposes. This Article explains the underlying technologies and market developments for a law and policy audience to assess those proposals critically. The Article proceeds in three parts tracking three rounds of the Going Dark Debate. Round 1 covers the Crypto Wars of the 1990s, when U.S. export controls on strong encryption ultimately fell in 1999. Round 2 covers the period roughly 2010 to 2015, when encryption-in-transit became widespread but lawful access remained available through cloud providers, giving rise to what the authors called a “golden age of surveillance” rather than a period of going dark. Round 3 addresses the current debate over E2EE, where no entity between sender and recipient can read the plaintext...

AI Speeds Up Malware Development, Not Its Success Rate: Analysis

SecurityWeek

A recent analysis by Palo Alto Networks' Unit 42 examined 405 malware samples that are linked to artificial intelligence. The findings revealed that while AI can accelerate the development of malware, it does not necessarily improve its success rate. Out of the analyzed samples, only 12 managed to reach production endpoints, which indicates that most AI-generated malware struggles to effectively infiltrate systems. This study is significant as it suggests that while cybercriminals may adopt AI to create malware more quickly, the effectiveness of these tools remains limited. Companies and security teams should continue to focus on traditional defenses as the majority of AI-linked malware is not successfully deployed.
