    • Scalable FPGA fabric for parallelising 2D-surface trajectory cost calculations: Design and Evaluation of Application and Hardware 

      Jana, Dibyajyoti (Master thesis, 2014)
      One way of simplifying the two dimensional trajectory cost computation is to partition the 2D domain (i.e. the map ) into a grid of unit squares, and approximate the cost functions by constants within these sub-domains ...
    • Seamless Access to Home Content 

      Høiby, Ola (Master thesis, 2006)
      This thesis documents the mobile phone authentication in the data world and evaluate potential methods for seamless authentication. Telenors Mobil's authentication tool and Wap Gateway have been configured to provide the ...
    • Security in Offline Web Applications 

      Svartberg, Anja (Master thesis, 2009)
      Offline Web applications are increasingly popular. The possibility to have both the advantages of Web applications and traditional desktop applications is exiting. An offline Web application can be accessed from all ...
    • Security of QKD-systems with detector efficiency mismatch 

      Lydersen, Lars Vincent van De Wiel (Master thesis, 2008)
      The rules of quantum mechanics makes it possible to exchange a secret key at a distance. This is called quantum key distribution (QKD). In theory the key exchange can be made completely secure. Real QKD implementations ...
    • Security of quantum key distribution source 

      Simonsen, Eivind Sjøtun (Master thesis, 2010)
      Cryptography has begun its journey into the field of quantum information theory. Classical cryptography has shown weaknesses, which may be exploited in the future, either by development in mathematics, or by quantum ...
