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