A SECURE CLOUD COMPUTING ARCHITECTURE EMPLOYINGHYBRID CRYPTOGRAPHIC MECHANISMS

Abstract

Cloud computing has become a dominant paradigm for delivering scalable and ondemand computing services over the Internet. However, the increasing adoption of cloud platforms has raised significant concerns regarding data confidentiality, integrity, and secure access control. Traditional security mechanisms often fail to provide comprehensive protection against modern cyber threats. This paper proposes a secure cloud computing architecture that employs hybrid cryptographic mechanisms to enhance data security. The proposed model integrates symmetric and asymmetric encryption techniques along with secure key management to protect sensitive data stored and transmitted in cloud environments. By combining the strengths of multiple cryptographic algorithms, the framework ensures improved resistance against unauthorized access and data breaches. Experimental evaluation demonstrates that the proposed approach achieves higher security with acceptable computational overhead. The results confirm the effectiveness of hybrid cryptography in safeguarding cloud-based systems
