Security against network attacks in supervisory control systems
Cyber-physical systems (CPSs) integrate computing and communication capabilities to monitor and control physical processes. In order to do so, communication networks are commonly used to connect sensors, actuators, and controllers to monitor and control physical systems. The use of communication …

Techniques for design and implementation of physically unclonable functions
… unclonable functions (PUFs) provide a basis for many security, and digital rights management protocols. PUFs exploit the unclonable and unique manufacturing variability of silicon devices to establish a secret. However, as we will demonstrate in this work, the classic delay-based PUF structures …

Evaluating the Proliferation and Pervasiveness of Leaking Sensitive Data in the Secure Shell Protocol and in Internet Protocol Camera Frameworks
In George Orwell’s `nineteen eighty-four: A novel', there is fear regarding what “Big Brother”, knows due to the fact that even thoughts could be “heard”. Though we are not quite to this point, it should concern us all in what data we are transferring, both intentionally and unintentionally, and …

Micro-Moving Target IPv6 Defense for 6LoWPAN and the Internet of Things
The Internet of Things (IoT) is composed of billions of sensors and actuators that have varying tasks aimed at making industry, healthcare, and home life more efficient. These sensors and actuators are mainly low-powered and resource-constrained embedded devices with little room for implementing IP …

Empirically understanding the global impact of migration to DNS-over-HTTPS
It has long been established that using DNS-over-UDP poses multiple threats to security and privacy ranging from Man-in-the-Middle-attacks to your ISP keeping a track of what websites you are visiting. To overcome this the industry actors and researchers have come up with DNS-over-Encryption which …

Security threats to the MAC-layer in wireless networks
… control (MAC) protocol security is important in wireless networks due to the lack of physical access control that normally exists in wired networks in the form of connecting a cable. Most efforts in standards organizations and academic research focus on the requirements of confidentiality and …

Physical layer security for IoT applications
The increasing demands for Internet of things (IoT) applications and the tremendous increase in the volume of IoT generated data bring novel challenges for the fifth generation (5G) network. Verticals such as e-Health, vehicle to everything (V2X) and unmanned aerial vehicles (UAVs) require …

Design and Implementation of a Secure Communication Architecture
Internet communications transitioned from the traditional client-server model to the cloud model and are going towards a decentralized hybrid model. The communications are protected by the traditional security protocols. The participants (especially, server-side) are authenticated using a …

Securing Cognitive Radios with a Policy Enforcer and Secure Inter-component Transport Mechanisms
… It is widely believed that Software Defined Radios (SDRs) and Cognitive Radios (CRs) are the key enabling technologies to address these problems. The reconfigurability of SDRs combined with the decoupling of policies and the platform in policy-based radios poses a new technical problem …

An investigation to cybersecurity countermeasures for global internet infrastructure.
The Internet is comprised of entities. These entities are called Autonomous Systems (ASes). Each one of these ASes is managed by an Internet Service Provider (ISP). In return each group of ISPs are managed by Regional Internet Registry (RIR). Finally, all RIRs are managed by Internet Assigned …

A clean slate approach to secure wireless networking
… network protocols have been developed for performance. Subsequently, as attacks are identified, patches or defenses have been developed. This has led to an ``arms race,'' where one is never confident about what other vulnerabilities may be exposed in the future. We seek to reverse this process. …
