Abstract

With the rapid development of Internet of Things (IoT) technology, the interconnectivity of massive devices has brought unprecedented security challenges. This paper focuses on the application dilemmas of computer security protocols in IoT environments, aiming to explore the compatibility issues between existing security mechanisms and IoT architectures. By conducting an in-depth analysis of mainstream IoT application scenarios and integrating cryptographic theories with network communication principles, a security evaluation model suitable for resource-constrained environments has been constructed. The study reveals that traditional security protocols exhibit inefficiencies and excessive energy consumption when dealing with low-power, large-scale node networking. To address these issues, an optimized solution combining lightweight encryption algorithms with distributed authentication mechanisms is proposed, effectively enhancing the overall system security and operational efficiency. Experimental results demonstrate that this solution reduces communication overhead by 30% and shortens authentication latency by 45%, while ensuring data integrity and confidentiality. This research provides new insights into the design of IoT security protocols and holds significant implications for promoting the healthy development of intelligent IoT ecosystems.
