Modified AES based Algorithm for mPEG-4 and H.264 video encryption
(Aksaray Üniversitesi Fen Bilimleri Enstitüsü, 2017) Haj, Farhad M.; Tolun, Mehmet Reşit
Nowadays data security has become the most global issue after global warming. Expectations about a world war in the field of data seem on the horizon. The internet connects all the people through many ways, such as e-mails or voice massages or even video calls. However, the flow of data between the source and destination which is the basic operation of the Internet, can by interrupted by another user or intruder. In order to prevent this intervention there are security algorithms meant to encrypt all the bits from starting point of flow up to the end point. The most widely used flow of data in the Internet is video streaming which takes about 80% of the data flow. In this thesis AES algorithm is used to encrypt the video streaming data. The present research aims to maintain a secure path for a video between the source and the destination by modifying and optimizing the existing AES data securtity algorithm. Amongst the analysed parameters are, PSNR, encryption time, and overhead bit through encryption with compression.
