A Novel Security Mechanism for Cloud based System using Blockchain Technology

Abstract

Different techniques are available to preserve data safety and privacy. Every program's goal should be to obtain confidentially, Integrity, and availability (CIA). The existing centralized cloud services, on the other hand, of CIA qualities. Distributed system archiving should be used in conjunction with blockchain systems to improve data safety and management approaches. It efficiently aids in the protection of data against manipulation and the deletion of a sample of data. A chain of blocks connects that hold data in a blockchain. Every block contains a hash function that would be recorded in the successive stages. After the decryption technique is applied, the information is transformed into an unintelligible form. To recover the original comment, the targeted user must know the secret that was used during the encryption algorithm. As a result, the odds of information alteration were reduced. The SHA-512 Hashing technique should be used in an application. The method exploits were utilized in a variety of applications to data protection was necessary, such as text digests, passcode validation, key exchange, but also blockchains. Information becomes safer and more dependable when various methodologies are combined. Nevertheless, the information's safety could be improved with the use of several techniques. Due to the major properties of the technique, Advance Encryption Standard (AES) was utilized to encrypt and decrypt the information.
