Safevault: Preventing Cloud Data Breaches Using ECC and Token-Based Access

Abstract

However, the centralized cloud storage poses a great threat to the security and privacy of the user. In the digital world, cloud storage is one of the most fundamental components of data storage and online services. In the traditional centralized approach, the data, including user information, credentials, and other access information, is stored centrally. This approach is highly vulnerable to attacks and data breaches. The main objective of the proposed research is to develop a system that improves the security, privacy, and control of the data, as well as providing a secure environment for storing and sharing digital assets. The system uses the Blockchain technology and the InterPlanetary File System (IPFS) to provide secure and tamper-proof storage. In the proposed system, Elliptic Curve Cryptography (ECC) is used to ensure the highest level of encryption using the smallest key sizes. In addition, the proxy re-encryption method is used to ensure the secure sharing of data among authorized users without revealing the original encryption keys. Zero-Knowledge Proof (ZKP) is used to ensure the highest level of privacy by verifying the user's authorization without revealing the actual credentials. The combination of decentralized storage, blockchain-based verification, and advanced cryptographic techniques provides a robust solution for mitigating cloud security threats, ensuring confidentiality, integrity, and transparency, and fostering a trustworthy environment for both individuals and organizations.
