In this research, we consider exploiting the large volume of audio/video data streams in compressed video clips/files for effective steganography. By observing that most of the distributed video files employ H.264 Advanced Video Coding (AVC) and MPEG Advanced Audio Coding (AAC) for video/audio compression, we examine the coding features in these data(More)
Security of large scale densely deployed and infrastructure-less wireless networks of resource limited sensor nodes requires efficient key distribution and management mechanisms. Key management is an important area of research in Wireless Sensor Networks (WSN), because resource constraints make security protocols difficult to be implemented. Key(More)
