Cloud data security and various cryptographic algorithms

Abstract

<p>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.</p>

The potential of ChatGPT technology in education: advantages, obstacles and future growth

“…Learning institutions must give priority to ensuring the security and confidentiality of the information entrusted to them, including personal information, grades, and student records. The installation and implementation of proper safeguards, secure communication protocols, access controls and user authentication, and regular monitoring and auditing of data access can help mitigate such security risks [13], [33], [34].…”

Harnessing the power of blockchain technology to support decision-making in e-commerce processes

“…Businesses can be confident that the agreed-upon terms will be implemented as planned, allowing them to make confident decisions. The transparency and traceability of blockchain also provide a high level of trust by allowing participants to verify the authenticity and transaction reliability, thereby reducing fraud risk or counterfeit products [42], [43]. With trust and security features, businesses can make well-informed decisions toward partnerships, customer engagement, and risk management, leading to improved outcomes and increased trust among stakeholders.…”

“…Blockchain technology provides inherent security benefits, concerns regarding data privacy, and confidentiality persist [43], [48]. Future research should focus on developing privacy-enhancing technologies within blockchain-based platforms, such as zero-knowledge proofs and secure multiparty computation, to address these concerns.…”

An Efficient and Secured Big Data Storage in a Cloud-based Environment Using Hybrid Cryptography Algorithm and Rivest, Shamir, Adleman Algorithm

“…Enabling computational efficiency is equally important to ensuring safe communication since realtime applications impose fast and reliable processing. Technically, a cloud is a storage space for digitalized data spread across a number of servers that are overseen by cloud service providers (CSP) [9,10]. Cloud storage is widely utilized to allow for the storage of huge amounts of data known as big-data [11].…”
