Age of Information for Channels under Attack by an Adversary ​

Since the world is becoming increasingly digitized safeguarding sensitive data has become a paramount concern. In particular measuring information freshness or timeliness or Age of Information (AoI) is becoming essential. This metric enables us to better appreciate how well a system understands the observed processes from source to recipient viewpoint. Hence this thesis presents how AoI is associated with security challenges including data breaches or cyber attacks that pose serious threats to valuable information. Moreover, it outlines various solutions developed specifically in an attempt to curb such risks in an AoI context effectively. By conducting in-depth research on these issues. This thesis endeavors to provide a comprehensive understanding of their implications, delivery into the realm of game theory's applicability to the interactions between information transmitters and adversaries, exploring their objectives, strategies, payoffs, and equilibrium points. By investigating how game theory can shed light on the complexities of security and communication, this research aims to provide insights into the robustness and vulnerabilities of information dissemination networks against intentional jamming attacks. The analysis contributes to a deeper understanding of the interplay between information dissemination, adversarial actions, and strategic decision-making, fostering the development of more resilient and secure communication protocols. The thesis addresses important issues such as examining how the Information Age is connected with security issues. It aims to help us better understand this ever-changing field. The detailed information here provides the information needed by academics interested in information security or communication systems. It is also useful for people making decisions about rules and policies in these areas.
