  Video Steganography System using Chua Circuit for Data Encryption

  By Satyakam ., Preethi V. Aithal, Rashmi .

  Abstract: Data transmitted over the Internet is becoming more and more prone to hacking. Therefore, network security has become key concern for everyone. Over the years cryptography and steganography has evolved as two branches of information security. The paper combines chaotic cryptography and video steganography to provide a two tiered protection for the message to be transmitted over any network. The message is first encrypted and made unrecognizable using Chua cryptography. …

  Observer-based Control Design and Stability Analysis of Networked Hammerstein Systems

  By Satyakam .

  Abstract: In this paper, an attempt has been made to design observer for Networked Control System (NCS) with random delays. The NCS has been modeled as a Hammerstein system, a cascade combination of static non-linearity and LTI system. Luenberger Observer and Kalman Filter have been used to estimate the system states. Simulation results have been presented which result in stable overall Hammerstein systems, with improvements over existing control procedures.Keywords: Networked Control …
