Research on Secure Cryptographic Cloud Communication focuses on protecting data confidentiality, integrity, and authenticity during transmission and storage in cloud environments. Modern approaches employ hybrid cryptographic frameworks, combining symmetric and asymmetric encryption techniques, elliptic curve cryptography, and advanced key management schemes to ensure secure communication channels. Emerging methods integrate quantum key distribution and multiparty privacy-preserving protocols to counter evolving cyber threats and unauthorized access. Three-layer and multi-stage encryption algorithms enhance robustness while maintaining efficiency, and comparative studies guide the selection of optimal protocols for diverse cloud architectures. Overall, secure cryptographic cloud communication provides a resilient, privacy-preserving, and trustworthy framework for data exchange and storage across distributed cloud systems.
