  abstract = {Algorithmic parameterization and hardware architectures can ensure secure transmission of multimedia
 data in resource-constrained environments such as wireless video surveillance networks, tele-medicine frameworks for distant
 health care support in rural areas, and Internet video streaming. Joint multimedia compression and encryption techniques can 
significantly reduce the computational requirements of video processing systems. We present an approach to reduce the 
computational cost of multimedia encryption, while also preserving the properties of compressed video (useful for scalability,
 transcoding, and retrieval), which endanger loss by naive encryption. Hardware-amenable design of proposed algorithms 
makes them suitable for realtime embeddedmultimedia systems. This approach alleviates the need of additional hardware for 
encryption in resourceconstrained scenario, and can be otherwise used to augment existing encryption methods used for content 
delivery in Internet or other applications. In this work, we show how two compression blocks for video coding: a modified
 frequency transform (called as Secure Wavelet Transform or SWT) and a modified entropy coding scheme, (called Chaotic Arithmetic Coding (CAC)) can be used for video encryption. Experimental results are shown for selective encryption using proposed schemes.}
