Title of Talk: Substitution Boxes for Image Encryption Applications in Highly Auto-Correlated Data

Abstract: With the advent of digital communication, the security of digital images during transmission and storage has become a major concern. Traditional Substitution Box (S-Box) replacement algorithms frequently fail to successfully conceal information inside highly auto-correlated parts of an image. The security challenges raised by three popular S-box substitution methods—single S-box, multiple S-boxes, and multiple rounds with multiple S-boxes—particularly when dealing with images with highly auto-correlated pixels and lower grey scales will be addressed in this talk. We will discuss a novel technique known as SRSS (Single Round Single S-Box encryption scheme) that overcomes the existing methods’ latency and large computing requirements. To effectively encrypt the plaintext image, SRSS uses a single S-box for substitution in just one round. Furthermore, this work introduces a new method CROSS (Chaos-based Random Operation Selection System), which eliminates the need for several S-boxes, lowering the complexity of the encryption system.

Title of Talk: Nanophotonics control of thermal radiation for energy applications

Abstract: Thermal radiation represents a ubiquitous aspect of nature. Any object at finite temperatures emits thermal radiation due to thermally induced motion of particles and quasiparticles. The sun at 6000 K and the cold universe at 3 K, representing the most important renewable energy resource and the ultimate thermodynamic heat sink, are all accessible through thermal radiation.  The ability to control thermal radiation therefore plays a fundamentally important role in energy applications. Nanophotonic structures, where at least one of the structural features are at a wavelength or sub-wavelength scale, can have thermal radiation properties that are drastically different from conventional thermal emitters, and offer exciting opportunities for energy applications. In this talk, I will discuss recent developments of nanophotonic control in thermal radiation, and highlight some exciting energy application opportunities, including radiative cooling and energy harvesting systems.

Title of Talk: Path Loss Models of 5G mmWave Communication System

Abstract: Wireless networks generally include some form of radio transmission for broadcasting and receiving wireless signals across a specified range of electromagnetic radiation spectrum, commonly referred to simply as spectrum.  The signal power in wireless communication systems is influenced by its surroundings; primarily, it will be affected by the path difference, operating frequency, and environmental effects. This makes it extremely challenging to plan any communication system that will provide better signal strength. Therefore, large scale path loss models are considered to estimate the path loss at various frequencies, distances, and in various environments. In this keynote, it will focus on the UMi, Uma and RMa environments to estimate the LOS and NLOS path loss for frequencies from 0.5-100 GHz. In the millimeter wave frequency range, a comparison is made between the path loss observed and the path loss models created by different standard organizations. The simulation results demonstrate that the 5GCM model is an optimized path loss model in the urban micro environment, similarly 3GPP model is an optimized path loss model in UMa and RMa environments. These optimized models produce enhanced path loss compared to the other path loss models. These optimized models could be used by the service providers to enhance the quality of service in 5G wireless networks.
