Abstract:

Cloud computing has transformed data storage and data accessibility, but it is still susceptible to unauthorized access and data breaches. This paper presents a unique Security Authenticated Key Protocol to establish a secure, encrypted communication channel between cloud service providers and end users. The protocol focuses on preventing threats such as man-in-the-middle attacks and credential stuffing by adding a multi-factor authentication layer to the key exchange process. To test the performance of this protocol, researchers have used a custom dataset comprising 402 cases that represent various network traffic patterns, login attempts, and an adversary's artificial intrusion. The study used the latest and greatest simulation software, and the primary consideration was the CloudSim framework integrated with Python cryptography libraries to simulate performance. Our results show that the offered protocol significantly reduces authentication latency while maintaining a high degree of cryptographic strength. The findings show that the computational overhead is reduced relative to past practice, ensuring security without compromising system performance. This study presents a scalable framework for ensuring information confidentiality in a distributed setting and establishes a balance between protection and business competitiveness.
