Cryptography in Secure Cloud Computing
Abstract
Cloud computing offers cost efficiency and scalability but introduces significant security concerns related to data control. Cryptography addresses these concerns by ensuring data confidentiality, integrity, authenticity, and availability . This research document provides an in-depth analysis of cryptographic techniques in cloud computing, including symmetric and asymmetric encryption, homomorphic encryption, and post-quantum cryptography. It critically evaluates the strengths and limitations of current approaches, particularly in key management and data-in-use protection, and explores future directions and a proof of concept to enhance cloud security.
