Cloud computing is a current running trend all over the world. There are a lot of cloud computing models like PaaS, SaaS, and IaaS. Cloud services growth makes many changes in the computing world. A lot of service providers of the cloud are available in the computer world. Protecting the data or information in the cloud database server is the only area of concerns in the cloud computing. Cryptography method is usually used to protect data in cloud databases. It is a method that transforms the sensitive data into an unreadable form. Cryptography technique offers many asymmetric or symmetric algorithms to protect the data. This paper shows the AES algorithm and AES is based on many permutation, transformation and, substitutions.
