NOVEL ASPECTS OF CLOUD COMPUTING SECURITY USING CRYPTOGRAPHY

Abstract

A cloud computing network is an autonomous collection of linked computers that communicate with one another intelligibly and independently using various protocols. It is important that this communication be done securely. There are times when this security is compromised by various attacks. Therefore, symmetric and asymmetric cryptography algorithms are used to communicate securely. Data availability, confidentiality, integrity, non-repudiation, and authentication are all made possible with the aid of cryptography. With the help of a shared key between the sender and the recipient, each block of data that is processed by this newly suggested cryptography algorithm is encrypted. This algorithm has enhanced security features that make it more resistant to all kinds of attacks. These features support the speed and security of both the RSA and AES algorithms. This algorithm is more secure than previous ones because it has three stages of execution for encryption and decryption. You can use MATLAB R2019a to implement the suggested algorithm. Three factors, including the avalanche effect, performance, and security against different types of attacks, will be examined in relation to this suggested algorithm that goes through several stages of encryption and decryption.
