In the modern technology world, information security is very essential to communicate the confidential data between the networks. The cryptography is used to data transmission, information storage and also useful for system communication. for that, we implemented a high speed AES algorithm in order to provide the high security, reliability, safety for the transmitted data. The video is converted to image frames, then is converted to the VHDL codes in the MATLAB 2014a.The AES algorithm is used for transmitting the text, images, videos with available key values of the 128,198,256 bits. But, here the security is implemented with 128 key values of the AES algorithm for video cryptography in the VHDL implementation. The proposed system of the algorithm provides the high processing speed in the order of ps(>6800ps). The algorithm is implemented in ModelSim-Altera 6.3g_p1 (Quartus II 8.1) Web Edition. The video cartography is processed in video size of 8Mbps. The encryption and decryption is processed in VHDL with the digital output.Finally, the video is viewed by the single board computer Raspberry pi.
