1. 36. On Safe and Secure Communication in Process Automation

   Författare :Johan Åkerberg; Mats Björkman; Maria Lindén; Mikael Gidlund; Lutz Rauchhaupt; Mälardalens högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Science; datavetenskap;

   Sammanfattning : In the process industry, network and system security have become important since the introduction of Ethernet-based fieldbus protocols. As an example, a successful attack on a power plant, supporting large cities with energy, could result in a temporal but total power loss. Such attacks could be devastating for the society. LÄS MER

3. 37. State-based Channel Access for a Network of Control Systems

   Författare :Chithrupa Ramesh; Karl Henrik Johansson; Henrik Sandberg; Joao Hespanha; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; networked control; multiple access; event-based; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Wireless networked control systems use shared wireless links to communicate between sensors and controllers, and require a channel access policy to arbitrate access to the links. Existing multiple access protocols perform this role in an agnostic manner, by remaining insular to the applications that run over the network. LÄS MER

4. 38. Tailoring Pairwise Non-Orthogonal Multiple Access to the Requirements of Critical Cyber-Physical Systems

   Författare :Van-Lan Dao; Elisabeth Uhlemann; Le-Nam Hoang; Svetlana Girs; Fredrik Brännström; Mälardalens högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer Science; datavetenskap;

   Sammanfattning : Within the context of Industry 4.0, many devices have become more intelligent and connected, leading to challenges on how to meet the stringent requirements on latency and reliability in networks of critical cyber-physical systems. In particular, timely channel access and high reliability are of essence to guarantee real-time deadlines. LÄS MER

5. 39. Low-Voltage Analog-to-Digital Converters and Mixed-Signal Interfaces

   Författare :Prakash Harikumar; Jacob Wikner; Atila Alvandpour; Dag T. Wisland; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Analog-to-digital converters (ADCs) are crucial blocks which form the interface between the physical world and the digital domain. ADCs are indispensable in numerous applications such as wireless sensor networks (WSNs), wireless/wireline communication receivers and data acquisition systems. LÄS MER

7. 40. Performance Guarantees for Physical Layer Authentication in Mission-Critical Communications

   Författare :Henrik Forssell; Ragnar Thobaben; Stefano Tomasin; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Physical layer authentication; mission-critical communica- tions; worst-case performance; queueing delay performance; stochastic net- work calculus; optimal attack strategies.; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : As the application areas for wireless communications are expanding, we also see new security vulnerabilities arise due to the open nature of the wire- less medium. One particularly challenging problem is how to guarantee the security of emerging mission-critical communications, e.g. LÄS MER
