Objectives: This paper addresses the problem of secure data storage and sharing over cloud storage infrastructures. A secure, distributed cloud storage structure incorporating the blockchain structure is proposed that supports confidentiality, integrity, and availability. Methods/Analysis: The proposed structure combines two well-known technologies: one of them is the Ethereum Blockchain and its Smart Contracts and the other is the RSA encryption and authentication scheme. The Ethereum Blockchain is used as a data structure, which ensures data availability and integrity while RSA provides sensitive data confidentiality and source authentication. Findings: As a result, users of the proposed structure can trust it and be certain that they can securely exchange information through a publicly accessible and shared cloud storage. The application can be used either through a user interface (UI) or a command-line interface (CLI). Novelty /Improvement:The novelty of this work is that the system that is proposed could be used for secure data storage on the cloud as well as for file sharing and authentication verification. Also, secure data storage and file sharing are already offered by the proposed system. Doi: 10.28991/ESJ-2023-07-02-012 Full Text: PDF

“…It just needs to originate multiple ciphertexts to attain the requirement of hierarchical access because of that computational overhead is increased. So, He et al [12] had presented an effective hierarchical CP-ABE algorithm to reach fine-grained access control of multiple hierarchical files efficiently. The access structure of the proposed hierarchical CP-ABE algorithm was linear secret sharing method.…”

Due to the mobility of users in an organization, inclusion of dynamic attributes such as time and location becomes the major challenge in Ciphertext-Policy Attribute-Based Encryption (CP-ABE). By considering this challenge; we focus to present dynamic time and location information in CP-ABE with multi-authorization. At first, along with the set of attributes of the users, their corresponding location is also embedded. Geohash is used to encode the latitude and longitude of the user's position. Then, decrypt time period and access time period of users are defined using the new time tree (NTT) structure. The NTT sets the encrypted duration of the encrypted data and the valid access time of the private key on the data user's private key. Besides, single authorization of attribute authority (AA) is extended as multi authorization for enhancing the effectiveness of key generation. Simulation results depict that the proposed CP-ABE achieves better encryption time, decryption time, security level and memory usage. Namely, encryption time and decryption time of the proposed CP-ABE are reduced to 19% and 16% than that of existing CP-ABE scheme.

Every person in the world needs documents that prove their identity, graduation from the university, residence, marriage, and other essential records that must be safely handled. The credibility of the documents depends on the stamp seal imprints found in them belonging to the government entity, the source of the credibility. But recently, with the rapid development of technology, the number of forged documents and forged stamp seals imprints has increased tremendously, which has led to significant security and social problems. Most of the world's governments depend on securing documents by securing stamp seal imprints through using Ultra Violets inks and issuing them through a centralized environment, which contains many challenges and problems. Central repositories may have security issues such as a single point of failure challenge, data unavailability due to central system failures, or a Denial of Service (DoS) attack. Therefore, this paper will present a proposal that solves the challenges in electronic systems (complete digitalization) and paper systems (partial digitalization). This manuscript proposes a smart securing model to secure stamp seal imprints by encrypting data with stamp seal image of the seal and storing it as a block through the decentralized Blockchain platform. After that, a quick response code (QR) is created to access that block quickly and securely. Also, the stamp seal's hash image and the details of the stamp seal's data source in the blockchain provide a shared, immutable, and transparent history of the stamp seals without relying on any third party. After several experiments, the results proved an accuracy and security rate of stamp seals and documents that reached 98%, with a high retrieval speed. Thus, a safe, fast, and non-changeable environment was provided to retrieve necessary information and ensure its authenticity.
