Kripto sistemleri için kaos teorisini kullanarak bulut bilgisayar güvenliğini artırma

The safety of the information stored in the cloud has emerged as a primary worry in recent years alongside the expansion of cloud computing. Traditional encryption algorithms, such as Advanced Encryption Standard (AES), are susceptible to attacks, particularly when the keys are held on the cloud. This is because cloud providers encrypt data to protect it from unauthorized access. As a consequence of this, there is a requirement for an updated encryption method that offers a higher level of protection for data stored in the cloud. In this thesis, a modified version of the AES algorithm is proposed as a solution to the problem of ensuring the safety of cloud data by improving the key management and encryption procedure. In order to protect the secrecy, integrity, and authenticity of data stored in the cloud, a modified version of the AES algorithm makes use of a hybrid key management technique. This strategy combines the benefits of symmetric and asymmetric encryption. A randomized encryption procedure is also a part of the method. This process helps to ensure that the ciphertext is completely unique and makes it more difficult for adversaries to break the encryption. Using a cloud-based system, the purpose of this paper is to analyze the efficiency as well as the safety of a modified version of the AES algorithm. The evaluation will include a comparison of the modified AES algorithm with typical encryption algorithms, such as AES and RSA, in terms of security, efficiency, and scalability.

The findings of the evaluation will illustrate the efficacy of the modified AES algorithm in preventing illegal access to cloud data and preserving the confidentiality and safety of cloud-based systems.
