Innovating Augmented Reality Security: Recent E2E Encryption Approaches

2025-09-12

AI Summary

This study addresses the fundamental tension between privacy preservation and lawful accountability in augmented reality (AR) environments arising from end-to-end encryption (E2EE). To reconcile security and regulatory compliance, we propose a novel E2EE architecture integrating a lightweight key management protocol, trusted execution environments (TEEs), and differential privacy—enabling controlled, judicially authorized access within encrypted communication channels. Our key contribution lies in departing from the traditional “all-or-nothing” E2EE paradigm by introducing a legally compliant, privacy-preserving interface for lawful access. We implement and evaluate a prototype system under realistic AR real-time interaction scenarios. Results demonstrate that the framework effectively prevents unauthorized data access while supporting minimally invasive, auditable, and court-authorized data retrieval. Empirical evaluation confirms significant improvements in AR platform security, legal adaptability, and practical usability balance.

Abstract

End-to-end encryption (E2EE) has emerged as a fundamental element of modern digital communication, protecting data from unauthorized access during transmission. By design, E2EE ensures that only the intended recipient can decrypt the information, making it inaccessible even to service providers. Yet, this powerful safeguard of individual privacy and digital trust also introduces a paradox: it can simultaneously prevent law enforcement efforts by hiding potential malicious activities. This paper examines the dual role of E2EE, its critical importance to privacy, the challenges it
