Evaluation and Improvement of Security in Embedded Sensor Systems

by N.n.
Supervisor(s) Knut Øvsthus
Due date 2015/05/02
Status Planned
Problem description: Many industrial sensor networks use real-time data transmission over public networks (GPRS, the Internet, satellites) or private radio links or cables. These links are in principle possible to listen in to or monitor. With increasing awareness of security risks for information theft or distortion in sensor systems it is suspected that customers buying sensor network services will in the near future demand security as well as reliability.

Embedded systems often have limitations regarding data processing and internal memory. In addition there are typically limitations in data rates of the transmission medium.

The thesis will investigate what demands to security exists (if any) from governmental organs (Norwegian, European, globally) and what typical demands central actors in Norwegian industries demand. Coming trends for the future will also be evaluated. In addition the thesis will evaluate different possibilities for implementing security on already existing embedded sensor systems. This thesis will in the end be able to answer what might be necessary functionality to secure data information for data loggers that deliver sensor data to customers using open communication channels.

Methods and Tools: The tools and methods in this thesis are based on
  • A set of scenario, describing the challenges
  • A list of requirements being extracted from the scenarios
  • A description and evaluation of technologies and tools being candidates for solutions
  • A functional architecture/description of the envisaged system
  • An implementation of the core concepts
  • A demonstration of the solution
  • An evaluation of the solution, including a critical review of the descisions taken earlier
  • Conclusions
  • References
Time schedule The envisaged time schedule (for a long thesis/60 ECTS) is:
T0 0 starting month, T0+m denotes the month where the contribution to a certain chapter shall be finalized
T0+2 months: create an initial page describing the scenario
T0+5: Provide a list of technologies which you think are necessary for the thesis
T0+5: Establish the table of content (TOC) of the envisaged thesis. Each section shall contain 3-10 keywords describing the content of that section
T0+8: Provide a draft of section 2 (scenario) and 3 (technologies)
T0+10: Establish a draft on what to implement/architecture
T0+11: Set-up an implementation, testing and evaluation plan
T0+15: Evaluate your solution based on a set of parameters, keep in mind there is no such thing as a free lunch
T0+17: Deliver the thesis
Pre-Knowledge This thesis includes a reasonable amount of programming. The envisaged thesis is based on security and radio communications, thus expects the user to have followed at least two radio-or security-related courses

Metodar tenkt å brukast i oppgåva:

  • ROS-analyse: Evaluera kva grad av sikkerheit som må implementerast for ulike scenario basert på
    • Informasjonsverdi
    • Risiko for tap/endring av informasjon
    • Forventa krav frå omverd
      • Kva er hensiktsmessig/ønskeleg for eit (eller fleire) gitt system
  • Bestemme seg for ei løysing
  • Teste denne

This page provides hints on what to include in your master thesis.

Red line

Your thesis should have a "red line", which is visible throughout the whole thesis. This means you should mention in the beginning of each chapter how the chapter contributes to the "goals of the thesis".

Use of scientific methods

A thesis follows a standard method:

  • describe the problem (problemstilling)
  • extract the challenges. These challenges should be measurable, e.g. method is too slow to be useful to voice handover.
  • Analyse technology with respect to challenges. Don't write & repeat "everything" from a certain technology, concentrate on those parts (e.g. protocols) which are of importance for your problem


  • Wikipedia is good to use to get an overview on what is happening. But there is not scientific verification of Wikipedia, thus you should use wikipedia only in the introduction of a chapter (if you use text from wikipedia). Use scientific literature for your thesis.
  • Scientific library is "at your hand", you can get there directly from UiO: [[How to get access to IEEE, Springer and other scientific literature -> Unik/UiOLibrary]]
  • I suggest that references to web pages, e.g. OASIS, W3C standards, are given in a footnote. Only if you find white papers or other .pdf documents on a web page then you refer to them in the reference section.

Evaluation of own work

Perform an evaluation of your own work. Revisit the challenges and discuss in how you fulfilled them. Provide alternative solution and discuss what should be done (or what could have been done).
