Multi-way Cloud-Side Access Control for Encrypted Cloud Storage

Individuals support the incredible intensity of cloud computing, however can't completely believe the cloud providers to have protection delicate data, because of the nonattendance of client to-cloud controllability. To guarantee confidentiality, data administrators redistribute scrambled data rather than plaintexts. To impart the scrambled files to different clients, ciphertext-strategy attribute-based encryption can be used to direct fine-grained and administrator driven access control. Yet, this doesn't adequately get secure against different assaults. Numerous past schemes didn't concede the cloud supplier the capacity to check whether a downloader can decode. Along these lines, these files ought to be accessible to everybody open to the cloud storage. A noxious aggressor can download a great many files to dispatch monetary refusal of supportability assaults, which will to a great extent expend the cloud asset. The payer of the cloud service bears the cost. These worries ought to be settled in true open cloud storage. In this paper, we propose an answer for secure encoded cloud storages from EDoS assaults and give asset utilization responsibility. We present two conventions for various settings, trailed by execution and security examination. Furthermore, attribute-based control in the framework additionally empowers the cloud server to confine the entrance to those clients with a similar arrangement of attributes while protecting client security, i.e., the cloud server just realizes that the client satisfies the necessary predicate, however has no clue on the specific identity of the client

Cloud data security and various cryptographic algorithms

Cloud computing has spread widely among different organizations due to its advantages, such as cost reduction, resource pooling, broad network access, and ease of administration. It increases the abilities of physical resources by optimizing shared use. Clients’ valuable items (data and applications) are moved outside of regulatory supervision in a shared environment where many clients are grouped together. However, this process poses security concerns, such as sensitive information theft and personally identifiable data leakage. Many researchers have contributed to reducing the problem of data security in cloud computing by developing a variety of technologies to secure cloud data, including encryption. In this study, a set of encryption algorithms (advance encryption standard (AES), data encryption standard (DES), Blowfish, Rivest-Shamir-Adleman (RSA) encryption, and international data encryption algorithm (IDEA) was compared in terms of security, data encipherment capacity, memory usage, and encipherment time to determine the optimal algorithm for securing cloud information from hackers. Results show that RSA and IDEA are less secure than AES, Blowfish, and DES). The AES algorithm encrypts a huge amount of data, takes the least encipherment time, and is faster than other algorithms, and the Blowfish algorithm requires the least amount of memory space

Encrypted Data Sharing in Cloud data storage using Cloud Computing

To ensure confidentiality, data owners outsource encrypted data instead of plaintexts. To share the encrypted files with other users, Ciphertext-Policy Attribute-based Encryption (CP-ABE) can be utilized to conduct fine-grained and owner-centric access control. But this does not sufficiently become secure against other attacks. Many previous schemes did not grant the cloud provider the capability to verify whether a downloader can decrypt. Therefore, these files should be available to everyone accessible to the cloud storage. which will largely consume the cloud resource. The payer of the cloud service bears the expense. Besides, the cloud provider serves both as the accountant and the payee of resource consumption fee, lacking the transparency to data owners. These concerns should be resolved in real-world public cloud storage. In this paper, we propose a solution to secure encrypted cloud storages and provide resource consumption accountability. It uses CP-ABE schemes in a black-box manner and complies with arbitrary access policy of CP-ABE. We present two protocols for different settings, followed by performance and security analysis
