Cryptography and the Frontier of Privacy
This article seeks to provide an in-depth exploration of the applications of cryptography in the context of cybersecurity. We'll cover a variety of complex and essential topics, including symmetric and asymmetric key cryptography, encryption algorithms, authentication protocols, digital signatures, and key management. In addition, we will examine practical use cases where encryption plays a critical role in mitigating cyberthreats, such as man-in-the-middle attacks, data tampering, and identity theft, and the contradictions with GDPR and LGPD regulations that have angered governments and law enforcement.
Interview with Chirath De Alwis
I would like to identify myself as a person who loves doing research in the cybersecurity domain and also loves sharing my knowledge and research findings with the community for the betterment of the community.

Unlocking the Orbital Domain: Digital Forensics in Satellite and UAV Technologies
The evolution of digital technology has significantly broadened the scope of digital forensics, a field traditionally tethered to terrestrial digital systems. The advent of satellite and Unmanned Aerial Vehicle (UAV) technologies has opened up new frontiers, marking a significant stride towards a global digital ecosystem. These technologies are the linchpins in a gamut of critical sectors including global communication, navigation, and surveillance. The imperative to safeguard these systems against burgeoning cyber threats has catalyzed the emergence of satellite and UAV digital forensics. This discourse endeavors to traverse the nascent field of satellite and UAV digital forensics, elucidating on the symbiotic relationship between emerging digital forensic tools, methodologies, and the inherent challenges.
Satellite Forensics
Satellites have become indispensable elements of modern-day life. This technology is playing a vital role in communication, navigation, streaming services, Earth observation, and scientific research. As our dependence on satellite technology grows, the number of vulnerabilities grows with it; so does the need for satellite forensics, a specialized field focused on gathering and analyzing data from satellites to investigate incidents, such as space debris collisions, unauthorized access, or security breaches.
Unlocking Mysteries Beyond Earth from Above: The World of Satellite
Satellites, sometimes called “Digital Television”, orbiting high above the Earth's atmosphere, have become essential tools for communication, navigation, weather monitoring, and national security, but there are also natural satellites. For example, Earth is a satellite because it orbits the sun, and the moon is a satellite because it orbits the Earth. Figure 1 shows the typical satellite architecture. Dotted orange arrows denote radio links; solid black arrows denote ground network links. While their main functions are recognized, they also play a vital role in forensic investigations, helping unravel mysteries from above and provide valued insights into numerous events and occurrences. Satellite forensics, a quite promising field, involves the investigation and analysis of satellite images and data to track information pertinent to legal and investigative processes.
