A large amount of information is being communicated in the form of video in the present era of time. As the communication channels are advancing and becoming more able to transfer large amounts of data, this amount of video is going to further increase. A method to protect video contents from unauthorized access is known as a video encryption scheme. This paper first surveys the literature to identify most desired features of an encryption algorithm. Then a classification has been drawn according to their characteristics. After that, some of the algorithms are discussed and their working has been explained briefly. At the end a comparison has been shown displaying their performance on a few chosen parameters.
