Abstract
A large number of computers which are linked, workable and organized called cloud computing. In the cloud computing area, many challenges like security, reliability, execution, and balancing of the load. The most important of these issues is cloud security. In this paper, we describe the algorithm which is used to improve cloud security. The proposed algorithm has been designed and implemented for generating dynamic keys in cloud computing based on multiple techniques. These techniques in our proposal have used the coding, permutations and reorder bit by the search method in artificial intelligence. Also, it depends on polynomial equations to expand the original key. The algorithm has the ability to manage clients, generating secret keys of varying length and damage the key after a period of use. Also, the proposed block cipher algorithm has been designed and implemented to protect the data that is sent between clients with high complexity based on a number of techniques.
