Title of Talk 1: Cyber Security: Challenges and Evolving Solutions

Synopsis: As the digital landscape continues to evolve, so too does the need for advanced cyber security measures. In recent years, cyber security has increasingly shifted focus to address new and emerging threats driven by technological advancements and sophisticated cyber attack strategies. The growing adoption of the digital technologies, cloud computing, and remote work infrastructures has expanded the attack surface, making it more challenging for organizations to protect their digital assets. The talk elaborates the current challenges of cyber security and how the recent security techniques such as Elliptic Curve Cryptography (ECC), Identity Based Cryptography (IBC), Attribute Based Encryption (ABE) and Post Quantum Cryptography (PQC), are playing important role for preserving the CIA goal.

Title of Talk 2: Latest Security Challenges and Solutions in Internet-of-Things Enabled Smart Infrastructure

Synopsis: The Internet of Things (IoT) has revolutionized industries by connecting billions of devices, but this vast network of interconnected systems has introduced significant security vulnerabilities. As IoT devices proliferate across sectors like healthcare, smart cities, and industrial automation, they become attractive targets for cybercriminals. One of the primary challenges is the inherent insecurity of many IoT devices, which are often underpowered and lack robust security features, leaving them susceptible to attacks such as data breaches, botnet compromises, and denial-of-service attacks. Additionally, the decentralized nature of IoT networks, combined with the lack of standardization in security protocols, creates complexity in securing devices and communications. The communication channels between IoT devices are often inadequately encrypted, exposing sensitive data to interception and exploitation. Privacy concerns further complicate the IoT landscape, as these devices collect vast amounts of personal data, making them prime targets for misuse. The rapid scale of IoT deployments also presents challenges in managing security across a large number of diverse devices, many of which may be deployed in remote or hard-to-reach locations. To address these security challenges, the talk demonstrates about the detail solutions such as end-to-end encryption, device authentication, and the adoption of zero-trust architectures which are very essential to implement robust security standards and practices, ensuring the safe deployment of IoT devices in an increasingly connected world.

Title of Talk 3: Content Centric Network: Overview and Future Scopes

Synopsis: Initially, Internet was designed with the goal of sharing resources. With the recent technological advancement and huge information need, Internet has gradually shifted from resource sharing mode to information sharing mode. To meet the demands of current Internet usage pattern, content centric network (CCN) is envisaged as a clean-slate Internet architecture as the future Internet in parallel with IP-based network. This talk will focus on the b
