1. 1. Information-theoretic Privacy and Secrecy in Biometric Identification and Authentication

   Författare :Linghui Zhou; Tobias J. Oechtering; Mikael Skoglund; Hideki Yagi; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Information theory; identification; authentication; privacy; secrecy; Informationsteori; identifiering; autentisering; integritet; sekretess; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Nowadays, biometrics are more and more deployed to reinforce traditional authentication or identification that uses keys, passwords, etc. Biometric identification and authentication have been studied from various information-theoretic perspectives, where privacy and secrecy are two important aspects.

3. 2. Performance Guarantees for Physical Layer Authentication in Mission-Critical Communications

   Författare :Henrik Forssell; Ragnar Thobaben; Stefano Tomasin; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Physical layer authentication; mission-critical communica- tions; worst-case performance; queueing delay performance; stochastic net- work calculus; optimal attack strategies.; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : As the application areas for wireless communications are expanding, we also see new security vulnerabilities arise due to the open nature of the wire- less medium. One particularly challenging problem is how to guarantee the security of emerging mission-critical communications, e.g. LÄS MER

4. 3. Social Networks and Privacy

   Författare :Oleksandr Bodriagov; Sonja Buchegger; Melek Ӧnen; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; social networks; privacy; decentralized; encryption-based access control; Computer Science; Datalogi;

   Sammanfattning : Centralized online social networks pose a threat to their users’ privacy as social network providers have unlimited access to users’ data. Decentralized social networks address this problem by getting rid of the provider and giving control to the users themselves, meaning that only the end-users themselves should be able to control access of other parties to their data.

5. 4. 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

7. 5. Introducing public sector eIDs : The power of actors’ translations and institutional barriers

   Författare :Fredrik Söderström; Ulf Melin; Karin Axelsson; Agneta Ranerup; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; eID; electronic identification; introduction; eGovernment; Actor-Network Theory; institutional pressures; institutional barriers; eID; elektronisk identifiering; införanden; eFörvaltning; aktörsnätverksteori; institutionella tryck; institutionella hinder;

   Sammanfattning : The electronic identification (eID) is a digital representation of our analogue identity used for authentication in order to gain access to personalized restricted online content. Despite its limited and clearly defined scope, the eID has a unique role to play in information society as an enabler of public digital services for citizens as well as businesses and a prerequisite for the development of electronic government (eGovernment).
