1. 1. Distribution and Individual Watermarking of Streamed Content for Copy Protection

   Författare :Karl-Göran Stenborg; Robert Forchheimer; Peter Parnes; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Watermarking; Fingerprinting; Video distribution; Broadcast; Multicast; Telecommunication; Telekommunikation;

   Sammanfattning : Media such as movies and images are nowadays produced and distributed digitally. It is usually simple to make copies of digital content. Consequently illegal pirate copies can be duplicated and distributed in large quantities. One way to deter authorized content receivers from illegally redistributing the media is watermarking.

3. 2. Some aspects of cryptographic protocols : with applications in electronic voting and digital watermarking

   Författare :Björn Terelius; Douglas Wikström; Helger Lipmaa; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Cryptographic protocols are widely used on the internet, from relatively simple tasks such as key-agreement and authentication to much more complex problems like digital cash and electronic voting. Electronic voting in particular is a problem we investigate in this thesis. LÄS MER

4. 3. On large scale real time music distribution : security, reliability and heterogeneity

   Författare :Roland Parviainen; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Distribuerade datorsystem; Mobile and Pervasive Computing;

   Sammanfattning : This thesis presents a system for real-time large scale distributed music distribution, such as radio on the Internet. The existing technologies do not enable the full potential that broadcast media on the Internet can give, such as a very large number of interactive receivers. LÄS MER

5. 4. Analysis, Detection, and Mitigation of Attacks in Cyber-physical Systems

   Författare :Hanxiao Liu; Lihua Xie; Karl H. Johansson; Daniel Quevedo; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Security of cyber-physical systems; detection of cyber-attacks; POMDP; rollout approach; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Cyber-Physical Systems (CPS) offer close integration among computational elements, communication networks, and physical processes. Such systems play an increasingly important role in a large variety of fields, such as manufacturing, health care, environment, transportation, defence, and so on. LÄS MER

7. 5. Large scale and mobile group communication systems

   Författare :Roland Parviainen; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Distribuerade datorsystem; Mobile and Pervasive Computing;

   Sammanfattning : This doctoral thesis examines different attributes of large scale group communication systems such as scalability, security and mobility by studying two different prototype systems - mIR (multicast Interactive Radio) and MES (Mobile E-meeting Services). mIR is a system for large scale real-time music distribution, designed as an interactive radio system for the Internet.
