Abstract: This paper analyzes and applies scalable encryption methods to secure live video transmission in coherence with development of the Multiple Video Streaming and Compression (Multiple-VSCS) software, as applied for the Intelligent Traffic Management system. Motion images are captured, jointly compressed, encrypted and streamed real time via utilization of the 5.8 GHz OFDM Outdoor Wireless LAN network. Theoretical comparisons are made with current and previous encryption standards to ascertain the appropriate encryption solution. The selected standard is then developed and embedded into the H.263 video compression standard with different configurations at the DCT process to analyze the behavior of the encrypted stream rates with respect to quality of the scrambled images. The behavior is based on the amount of DCT coefficients subjected to encryption process with differences in the bit rates averaging between 40% and 90% under these conditions. © 2005 IEEE.
