Abstract
With the recent development of video compression methods, video transmission on traditional devices and video distribution using networks has increased in various devices such as drones, IP cameras, and small IoT devices. As a result, the demand for encryption techniques such as MPEG-DASH for transmitting streams over networks is increasing. These video stream security methods guarantee stream confidentiality. However, they do not hide the fact that the encrypted stream is being transmitted over the network. Considering that sniffing attacks can analyze the entropy of the stream and scan huge amounts of traffic on the network, to solve this problem, the deception method is required, which appears unencrypted but a confidential stream. In this paper, we propose the new deception method that utilizes standard NAL unit rules of video codec, where the unpromised device shows the cover video and the promised device shows the secret video for deceptive security. This method allows a low encryption cost and the stream to dodge entropy-based sniffing scan attacks. The proposed stream shows that successful decoding using five standard decoders and processing performance was 61% faster than the conventional encryption method in the test signal conformance set. In addition, a network encrypted stream scan method the HEDGE showed classification results that our stream is similar to a compressed video.

Summary
Sciancalepore, Giuseppe Piro and Currently, with the development of high-efficiency video codecs (HEVC), video traffic is used more often, accounting for approximately 80% of the total network traffic [1]. The world wide web consortium (W3C) recommends that the stream be transmitted by encrypting the video stream through a combination of asymmetric key and symmetric key encryption in HTML5 These protocols are easy to apply to video encoders designed without encryption; it is spotlighted as a technique that implements DRM for content-streaming platforms. Deception methods play an important role, especially within small networks, such as wireless LAN This is because in a small network, it is easy to analyze the data of all the hosts to which they belong through the router to physically find the location of the monitoring assets hidden within a short distance. Our proposed method for compressed video streams satisfies all of the above conditions as follows: First, our algorithm does not use cryptographic encryption methods to satisfy stealthy and can avoid entropy scans.
