Design and Implementation of a Robust Public Key Cryptographic Framework for Secure Communication in Cloud Computing Environments

Abstract

  Cloud computing offers the convenience of accessing data from anywhere through shared resources across insecure networks, raising critical concerns about confidentiality, authenticity, and data integrity. Security and privacy issues stem from factors such as data security and the lack of data confidentiality in open and shared environments. As the demand for resources grows and new technologies emerge, the need for secure data storage services in cloud environments becomes paramount. Public cloud service providers are often not fully trusted, exacerbating these concerns. This study proposes a robust security framework that combines homomorphic encryption with Elliptic Curve Cryptography (ECC) and the RSA algorithm to enhance data security in cloud computing. A comparative analysis of RSA and ECC is provided, demonstrating the strengths and weaknesses of each approach in securing cloud-based data storage.
