Privacy is key parameter of communication between or with internet of things. A symmetric block cipher that was established by the U.S. National Institute of Standards and Technology (NIST). However, some of the challenges arising from the use of this algorithm are computational overhead, use of a fixed S-Box and pattern problems, which occur when handling more complex multimedia data such as text, image and video. Many researchers have carried out research aiming at improving the algorithm's performance. This paper summarizes the various research work based on AES algorithms and observed some constraint using in internet of things application.
