1. 6. Improving Low-Power Wireless Protocols with Timing-Accurate Simulation

   Författare :Fredrik Österlind; Thiemo Voigt; Adam Dunkels; Per Gunningberg; Tarek F. Abdelzaher; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Low-Power Wireless Protocols; Wireless Sensor Networks; Contiki; Cooja; Simulation; Datavetenskap med inriktning mot datorkommunikation; Computer Science with specialization in Computer Communication;

   Sammanfattning : Low-power wireless technology enables numerous applications in areas from environmental monitoring and smart cities, to healthcare and recycling. But resource-constraints and the distributed nature of applications make low-power wireless networks difficult to develop and understand, resulting in increased development time, poor performance, software bugs, or even network failures.

3. 7. Language Support for Controlling Timing-Based Covert Channels

   Författare :Alejandro Russo; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; information-flow; language-based security; semaphores; non-interference; Haskell; library; concurrency; internal timing covert channel;

   Sammanfattning : The problem of controlling information flow in multithreaded programs remains an important open challenge.A major difficulty for tracking information flow in concurrent programs is due to the internal timing covert channel. LÄS MER

4. 8. A WCET Analysis Method for Pipelined Microprocessors with Cache Memories

   Författare :Thomas Lundqvist; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; real-time systems; data cache; infeasible paths; pipeline; instruction cache; dynamically scheduled processor; worst-case execution time; timing analysis; path analysis; timing anomaly;

   Sammanfattning : When constructing real-time systems, safe and tight estimations of the worst case execution time (WCET) of programs are needed. To obtain tight estimations, a common approach is to do path and timing analyses. LÄS MER

5. 9. Applications of Non-Blocking Data Structures to Real-Time Systems

   Författare :Håkan Sundell; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; shared memory; wait-free; snapshot; real-time; synchronisation; lock-free; timing information; non-blocking;

   Sammanfattning : This thesis is a major part of the results within a project called "Applications of wait/lock-free protocols to real-time systems". This project is funded by the national Swedish Real-Time Systems research initiative ARTES (www.artes.uu. LÄS MER

7. 10. Securing concurrent programs with dynamic information-flow control

   Författare :Pablo Buiras; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dynamic; lazy evaluation; LIO; Haskell; information-flow control; cache; covert channels; covert timing channels; concurrency;

   Sammanfattning : The work presented in this thesis focusses on dealing with timingcovert channels in dynamic information-flow control systems,particularly for the LIO library in Haskell.Timing channels are dangerous in the presence ofconcurrency. LÄS MER
