Abstract
With the rapid development of information technology, the application of computer networks has become increasingly widespread across various fields. However, this expansion has also led to more severe security threats, among which key management is a critical component for ensuring the effectiveness of computer security protocols. This study aims to explore key management strategies in computer security protocols to enhance the security and reliability of information transmission. Through literature analysis, theoretical derivation, and experimental simulation, this research provides a comprehensive examination of existing mechanisms for key generation, distribution, storage, update, and revocation. It was found that traditional key management approaches suffer from inefficiency and inadequate security. To address these issues, this study proposes a novel key management system based on blockchain technology. By leveraging the distributed ledger characteristics of blockchain, this system ensures secure and controllable key lifecycle management while improving operational efficiency. The innovation lies in the deep integration of blockchain technology with key management, establishing a dynamic key management model that meets modern network security requirements. This not only resolves problems associated with traditional key management but also offers new insights and technical support for the future development of computer security protocols, thereby playing a significant role in advancing the field of information security.
