Use of Cryptography in Cloud Computing: Enhancing Data Security and Privacy

Abstract: Strong security measures are now more important than ever to preserve data integrity and confidentiality as cloud computing grows in popularity. In cloud systems, cryptography is a fundamental tool for guaranteeing safe data transport, storage, and access. This study investigates the function of cryptographic methods in cloud computing, looking at key management systems, symmetric and asymmetric encryption, and homomorphic encryption. This study offers a thorough overview of how encryption technologies support data security and handle privacy concerns in distributed systems by examining modern cryptographic solutions and their use in cloud platforms. Keywords: cloud computing, cryptography, data security, encryption, privacy, public key infrastructure, homomorphic encryption, secure cloud storage
