Security Study Of Embedded Wireless Video Transmission System

Video surveillance systems have become the production, an essential part of life. Especially in recent years, with the computer digital technology, coding technology, broadband network technology, network-based IP video surveillance systems have become an increasingly widespread penetration into the security, education and other fields.With a variety of wireless network technology, based on wireless transmission of video surveillance systems are also increasing. Based on wireless network transmission of video surveillance systems than wired networks have more advantages, such as the arrangement of convenience, saving wiring of the human and material resources, with mobility, suitable arrangements in some unexpected locations. Because the second-and third-generation mobile technology, the use of extensive, now based on wireless transmission of video surveillance system to use more second-generation or third-generation mobile technology. Now, in some big cities, WIFI hot spots more and more, culminating in China, these cities WIFI wireless LAN coverage will keep rising. Therefore, it can be video surveillance terminal via WIFI wireless LAN into the city's Internet-connected video capture data to achieve long-distance transmission.This real-time transmission of video transmission security has been studied using AES symmetric encryption algorithm transmitted RTP packets for secure encryption, By calling the function EVP interface inside OPENSSL and modify the RTPLIB library to achieve.This paper presents a video transmission scheme that has broad application prospects, which applies not only to the application of remote monitoring system, but also in such as IPTV, VOD and distance education systems such as audio and video data to achieve the security of real-time transmission...
