- The industrial control systems (ICS) are using Real-Time Ethernet (RTE) protocols for many years. Today, Ethernet based control systems are widely used in industries. The Time Sensitive Networking (TSN) initiative will definitely push their further diffusion. With the introduction of Industry 4.0, production machines and their components have been connected to the Internet. Currently adopted RTE protocols do not require authentication, and hence may exchange data also with potentially malicious partners. In this paper, a selective Denial of Service (DoS) attack is presented. The proposed Selective Queue Saturation Attack (SQSA) is aimed to jam the message queue of the RTE communication stack in selected devices. The SQSA minimizes the chances of being detected by keeping its requirements (in term generated traffic) as low as possible. The SQSA has been applied to a real scenario based on PROFINET. The results of the use case demonstrate: the feasibility of the proposed attack; the reduced footprint compared to known DoS attacks (more than one thousand times less); and the selectivity of the attack, which can disrupt the realtime behavior of even a single target node inside the RTE network. © 2020 IEEE.

- In the last few decades, magnetic nanoparticles (MNPs) have had significant interest and became more remarkable in the field of oncology. MNPs has been proven to be the most suitable and promising nanomaterials for tumor targeting. This is mainly due to its intrinsic magnetic property which makes them characteristic agents to inducing magnetic hyperthermia and magnetic resonance imaging. The MNPs have usually been employed for cancer imaging through a passive approach. The modern techniques have enabled multimodal imaging, drug delivery, and specific cells targeting by MNPs. To synthesize more extravagant MNPs, the design criteria considerations, such as core metal, hydrodynamic size, shape, surface coating, and molecular functionalization, become very essential. In this chapter, the design parameters of MNPs including surface functionalization and physiochemical properties are summarized to overcome biological barriers. Furthermore, the chemistry of MNPs surface modification is discussed in detail to describe its nature and binding type.
