Abstract

With the rapid development of cloud computing technology, its openness and resource-sharing characteristics have brought numerous security challenges. Computer security protocols play an irreplaceable role in ensuring data security, access control, and privacy protection in cloud computing environments. This study aims to investigate the application of computer security protocols in cloud computing to enhance its security. By combining literature analysis with case studies, this research thoroughly examines the applicability and limitations of existing security protocols such as SSL/TLS and IPSec in cloud computing scenarios, and proposes improvement schemes based on attribute-based encryption and homomorphic encryption for cloud-specific issues like multi-tenancy and dynamic resource allocation. The results indicate that the improved security protocols can effectively address critical issues such as identity authentication, encrypted data transmission, and storage security in cloud computing environments, enhancing system security while ensuring high performance. Innovatively integrating traditional security protocols with emerging encryption technologies for application in cloud computing, this study provides theoretical foundations and technical support for building more secure and reliable cloud computing platforms, which is significant for promoting the healthy development of the cloud computing industry.
