While cloud storage seems dependable and scalable, the necessity for it is increasing every day. The intricacies involved in securing data in terms of privacy and confidentiality makes the storing and administration of user information at a remote location problematic. The cloud third party who is in charge of handling the issues concerned with data security present within the cloud systems could end up being an unreliable insider. In order to enhance the protection of data and ensure the confidentiality of information without any sort of interruption from cloud third parties, the current research provides an automated hybrid Cryptographic algorithm for Cloud Data Storage. Improved automated Asynchronous Encryption for Data Streams (AEDS) and enhanced automated Concurrent Encryption for Data Blocks (CEDB) are two encryption techniques that are used to achieve great performance and efficiency. We introduce a unique encryption method in Enhanced Automated Concurrent Encryption by transforming the fixed S-box in the conventional AES to a varying S-box utilising a Ternary Galois field and Complementary Ternary Galois field in the proposed work. Additionally, the Ternary Galois field and Complementary Ternary Galois field are employed to transform the matrix used for the AES mix column technique into a dynamic matrix.

“…The direction of eliminating the role of the CTP or reducing the potential risks of its existence has become the core of several recent studies that concern cloud security issues. In [16], S. Chakraborty et al, (2018) proposed an approach to ensure the integrity of data stored on a remote cloud server with the assistance of a trusted third-party auditor (TTPA). TTPA has been proposed as an expert agent in the data auditing process.…”

The need for cloud storage grows day after day due to its reliable and scalable nature. The storage and maintenance of user data at a remote location are severe issues due to the difficulty of ensuring data privacy and confidentiality. Some security issues within current cloud systems are managed by a cloud third party (CTP), who may turn into an untrustworthy insider part. This paper presents an automated Encryption/Decryption System for Cloud Data Storage (AEDS) based on hybrid cryptography algorithms to improve data security and ensure confidentiality without interference from CTP. Three encryption approaches are implemented to achieve high performance and efficiency: Automated Sequential Cryptography (ASC), Automated Random Cryptography (ARC), and Improved Automated Random Cryptography (IARC) for data blocks. In the IARC approach, we have presented a novel encryption strategy by converting the static S-box in the AES algorithm to a dynamic S-box. Furthermore, the algorithms RSA and Twofish are used to encrypt the generated keys to enhance privacy issues. We have evaluated our approaches with other existing symmetrical key algorithms such as DES, 3DES, and RC2. Although the two proposed ARC and ASC approaches are more complicated, they take less time than DES, DES3, and RC2 in processing the data and obtaining better performance in data throughput and confidentiality. ARC outperformed all of the other algorithms in the comparison. The ARC’s encrypting process has saved time compared with other algorithms, where its encryption time has been recorded as 22.58 s for a 500 MB file size, while the DES, 3DES, and RC2 have completed the encryption process in 44.43, 135.65, and 66.91 s, respectively, for the same file size. Nevertheless, when the file sizes increased to 2.2 GB, the ASC proved its efficiency in completing the encryption process in less time.
