1. 1. Simulering och analys av attacker riktade mot datalänklagret

   Kandidat-uppsats, Mälardalens universitet/Akademin för innovation, design och teknik

   Författare :Mohamad Jemmo; Kaler Laresé; [2022]
   Nyckelord :;

   Sammanfattning : OSI-modellens lager möjliggör kommunikation mellan nätverksenheter, men de kan också öppnaupp för attacker, eftersom det är svårare att upptäcka attacker mellan lager än attacker som skerdirekt på det lagret [1]. En attack på ett lager kan därmed öppna upp för attacker på andra lager. LÄS MER

3. 2. PHYSICAL LAYER SECURITY USING PSEUDO-RANDOM SEQUENCE KEY GENERATION

   Master-uppsats,

   Författare :Srihari Arolla; Naga Venkata Sai Teja Gurrala; [2018]
   Nyckelord :Physical Layer Security; Bit Error Rate; Key Error Rate; Pseudo Random Generator; Secret Key.;

   Sammanfattning : Nowadays, network security plays a major role in the field of wireless communications. Wired networks propagate electrical signals or pulses through cables. Whereas wireless signals propagate through the air. If wireless networks are left open and exposed to the outside world, there are high chances of being misused by others. LÄS MER

4. 3. Investigating the Neural Correlates of Perceived Social Isolation : Is Perceived Social Isolation Confined to the Social Brain?

   Kandidat-uppsats, Högskolan i Skövde/Institutionen för biovetenskap

   Författare :Kasper Löf; [2018]
   Nyckelord :Perceived Social Isolation; hypervigilance; social brain model; loneliness;

   Sammanfattning : Loneliness, or the perceived discrepancy of ones relationships in terms of quality, is known as Perceived Social Isolation (PSI). Studies have shown that PSI is both increasing and is correlated with health risks. Specifically, PSI is not only related with risks of mortality but is also linked with variations in the brain.

5. 4. Network Traffic Regulator for Diagnostic Messages in Modular Product

   Master-uppsats, KTH/Skolan för datavetenskap och kommunikation (CSC)

   Författare :Nikhil Thakrar; [2017]
   Nyckelord :Controller Area Network; CAN; Diagnostics; Scania; UDS; KWP; OBD; J1939; Network regulator; bandwidth management; Token Bucket; Traffic shaping; vehicle; bit stuffing; OSI model; arbitration;

   Sammanfattning : The aim of this thesis project is to explore a network traffic regulator using bandwidth management techniques that regulates data traffic with the objective to use the network bandwidth to its maximum capacity while ensuring that the network is not overloaded. The bandwidth in the existing network architecture is shared between two co-existing, distinct data flows for on-board communication and diagnostic communication in an in-vehicle network. LÄS MER

7. 5. A Vision Based Sensor System For Spacecraft Relative Navigation

   Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Författare :Sebastian Stauch; [2016]
   Nyckelord :;

   Sammanfattning : Docking is one of the crucial key elements in many aerospace applications and missions where despite all endeavors and precautions accidents and incidents occur far too often. Those events can lead in the worst case scenario to a total loss of the space system and payload. LÄS MER
