Latest research in Cryptography and Key Management Strategies for Cloud Security focuses on developing advanced cryptographic techniques and efficient key management frameworks to ensure secure data storage, sharing, and access in cloud environments. Studies highlight approaches such as attribute-based encryption, proxy re-encryption, homomorphic encryption, and hybrid cryptosystems to provide fine-grained access control and preserve data confidentiality across distributed cloud infrastructures. Research also addresses challenges in key generation, distribution, revocation, and lifecycle management while maintaining scalability and performance in multi-tenant systems. Additionally, integration with blockchain, automated key management services, and compliance with emerging security standards enhances trust, resilience, and overall cloud security, enabling robust protection against evolving cyber threats.
