Date: Nov 15, 2:05pm – 3:15pm Abstract: Traditional security frameworks, based on implicit trust models, prove inadequate for securing contemporary edge computing architectures. The dynamic nature of edge networks-characterized by heterogeneous IoT endpoints, distributed sensors, and computing nodes-necessitates a paradigm shift toward adaptive security frameworks. This study investigates the integration of Zero Trust Architecture (ZTA) within edge computing environments, focusing on continuous authentication mechanisms, granular access controls, and enhanced data privacy rotocols. We propose leveraging Distributed Ledger Technology (DLT) to establish immutable audit trails, ensure data integrity, and enforce privacy protocols across distributed edge nodes. While blockchain-based consensus mechanisms enable transparent policy enforcement and address trust deficits in decentralized systems, their implementation presents notable challenges, including consensus protocol scalability, latency constraints, and computational limitations of edge devices. Our research advances optimized cryptographic operations for resource-constrained environments, proposes lightweight consensus algorithms, and develops adaptive trust models responsive to dynamic network conditions. This framework demonstrates a systematic approach to securing edge computing infrastructures while maintaining operational efficiency against emerging cyber threats.
