Investigation and analysis of modern cryptographic methods with symmetric key in cloud computing

Cloud computing is a technology that uses the Internet and remote central servers to store and support data and applications. Cloud computing allows users to use applications without installation.It also allows access to personal files from any computer that has Internet access. Currently, cloud computing is one of the most attractive technologies in the world due to its cost reduction, flexibility and high scalability. However, cloud computing, which is used in many organizations today, faces a major challenge called security. One of the most important ways to ensure data security in cloud computing is to use encryption algorithms. One of the new cryptographic methods is based on symmetric key algorithms. Symmetric key algorithms play a major role in ensuring data security in cloud computing. Researchers in the field of security have tried to improve the performance of symmetric key cryptographic algorithms through various methods. In this research, these studies have been collected. Each of these methods has strengths and weaknesses that are expressed based on service quality parameters. The performance of these algorithms ensures improved data security in cloud computing.
