1. 1. Advancing Automation in Digital Forensic Investigations

   Författare :Irvin Homem; Panagiotis Papapetrou; Fredrik Blix; Indre Žliobaitė; Stockholms universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Digital Forensics; Machine Learning; Computer Forensics; Network Forensics; Predictive Modelling; Distributed Systems; Mobile Devices; Mobile Forensics; Memory Forensics; Android; Semantic Web; Hypervisors; Virtualization; Remote Acquisition; Evidence Analysis; Correlation; P2P; Bittorrent; Computer and Systems Sciences; data- och systemvetenskap;

   Sammanfattning : Digital Forensics is used to aid traditional preventive security mechanisms when they fail to curtail sophisticated and stealthy cybercrime events. The Digital Forensic Investigation process is largely manual in nature, or at best quasi-automated, requiring a highly skilled labour force and involving a sizeable time investment. LÄS MER

3. 2. Automotive Communication Security Methods and Recommendations for Securing In-vehicle and V2X Communications

   Författare :Nasser Nowdehi; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; V2X; security; automotive; vehicular communication; in-vehicle network;

   Sammanfattning : Today’s vehicles contain approximately more than 100 interconnected computers (ECUs), several of which will be connected to the Internet or external devices and networks around the vehicle. In the near future vehicles will extensively communicate with their environment via Vehicle to Vehicle (V2V) and Vehicle to Infrastructure (V2I), together called V2X communications. LÄS MER

4. 3. On the Secure and Resilient Design of Connected Vehicles: Methods and Guidelines

   Författare :Thomas Rosenstatter; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; security; secure communication; V2X; cyber-physical systems; resilience; in-vehicle network; automotive;

   Sammanfattning : Vehicles have come a long way from being purely mechanical systems to systems that consist of an internal network of more than 100 microcontrollers and systems that communicate with external entities, such as other vehicles, road infrastructure, the manufacturer’s cloud and external applications. This combination of resource constraints, safety-criticality, large attack surface and the fact that millions of people own and use them each day, makes securing vehicles particularly challenging as security practices and methods need to be tailored to meet these requirements.

5. 4. Towards Secure Synchronous Communication Architectures for Wireless Networks

   Författare :Kasun Hewage; Thiemo Voigt; Shahid Raza; Matthias Hollick; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datagram Transport Layer Security; Synchronous Transmissions; Denial-of-service Attacks; Transmission Control Protocol; Communication Security; Time Synchronisation; Optical Wireless Communication; Networked Embedded Systems; Internet of Things; Electrical Engineering with Specialisation in Networked Embedded Systems; Elektroteknik med inriktning mot nätverksbaserade inbyggda system;

   Sammanfattning : The vision behind the Internet of Things (IoT) revolves around creating a connected ecosystem where devices, people, and systems collaborate seamlessly, unlocking new possibilities, improving efficiency, and enhancing our daily lives. IoT encloses many device classes, including low-power wireless devices that rely on batteries or energy harvesting. LÄS MER

7. 5. Implementation and Evaluation of Signal Processing Circuits for Optical Communication

   Författare :Erik Börjeson; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adaptive Equalization; Carrier Phase Recovery; Digital Signal Processing; Application-Specific Integrated Circuits; Communication Systems; Fiber-Optic Communication;

   Sammanfattning : The digital signal processing (DSP) circuits used in the fiber-optic communication links that make up the backbone of the Internet can be a significant contributor the over-all power dissipation of a link. As the number of connected users and their bandwidth requirements are expected to continue to grow over the coming years, the development of power-efficient high-throughput DSP systems is a critical factor in enabling this growth.
