Software defined networking (SDN) is a novel networking paradigm which decouples control plane from data plane. This separation facilitates a high level of programmability and manageability. On the other hand, it makes the SDN controller a bottleneck and hence vulnerable to control plane saturation attack. One of the key mechanism to achieve control plane saturation is via TCP SYN flooding attack...
Computer networks today typically do not provide any mechanisms to the users to learn, in a reliable manner, which paths have (and have not!) been taken by their packets. Rather, it seems inevitable that as soon as a packet leaves the network card, the user is forced to trust the network provider to forward the packets as expected or agreed upon. This can be undesirable, especially in the light of...
Embedded devices for control and monitoring are becoming more powerful as technology evolves. It is common that these embedded devices are communicating through a local area network with other, sometimes more powerful, nodes for receiving and distributing commands and data gathering. This distributed system can then be connected to other systems over the Internet for data exchange, remote control...
To protect process control networks from cyber intrusions, preventive security measures such as perimeter defenses (for example, network firewalls and demilitarized zones) and secure versions of process control network protocols have been increasingly adopted or proposed. Although system hardening and fixing known vulnerabilities of existing systems are crucial to secure process control systems, intrusion...
It is often the case that safety-critical systems have to be reconfigured during operation because of issues such as changes in the systems operating environment or the failure of software or hardware components. The reconfiguration ability of system can recover operation in timely, also enhance the survivability of system by replacing current disabled configuration with a new one. In view of the...
Project-based learning is de-facto a great challenge for both students and instructors, and it can bring the number of advantages, or even disadvantages if suitable environment is not set. In DSP courses where special purpose architectures are studied, project-based learning should be carefully employed. On contrary to the approach in which student gets a project and instructor evaluates results of...
