Advanced Techniques for Cloud Data Security: Analysis of ECC, ECDSA, ZKP, and a Proposed Hybrid ZKP-ECDSA Scheme

Abstract

Due to its unmatched scalability and simplicity, cloud computing has become a critical component of contemporary IT architecture. However, serious worries regarding data integrity, security, and privacy have been brought up by the increased use of cloud services. The present study conducts a thorough investigation of the security of cloud data using cryptographic methods such as the Elliptic Curve Cryptography (ECC), the Elliptic Curve Digital Signatures Algorithm (ECDSA), and Zero Knowledge Proofs (ZKPs). We first explore the security of cloud data transmission and storage provided by ECC, and then we examine the role that ECDSA plays in data integrity and authentication. We also investigate how cloud security might be enhanced by privacy-preserving actions made available by Zero Knowledge Proofs (ZKPs). Interestingly, we introduce a new Hybrid ZKP approach that combines data integrity verification and encryption offered by ECDSA with the privacy-preserving ZKPs. We introduce a novel Hybrid Zero Knowledge Proof (ZKP) technique that combines ECC with ECDSA in order to achieve the best possible balance between privacy and security in cloud data management. This is an important inclusion. Furthermore, through theoretical evaluations and simulations, the potential of the proposed Hybrid ZKP technique for improving the privacy and security of data stored in the cloud is comprehensively examined.
