Abstract
Authentication is a crucial challenge for Internet of Things (IoT) security, especially in open, distributed and resource-constrained environments. Current methods have significant shortcomings in terms of efficiency, adaptability, and ability to cope with complicated security threats. Therefore, this paper proposes a lightweight authentication framework for Cloud-Edge-End, which integrates the enhanced Fast Authentication and Signature Trust for SM9 (FAST-SM9) algorithm and zero-trust Dynamic Re-authentication (zero-trust-DRA) mechanism. First, FAST-SM9 effectively reduces protocol overhead, and meanwhile ensuring security by organically integrating authentication and signature processes. Its architectural optimization reduces the number of communication rounds by 40% and simplifies trust negotiation between heterogeneous layers without affecting the integrity of encryption mechanisms.…
