1. 16. On User Perception of Authentication in Networks

   Författare :Charlott Lorentzen; Blekinge Tekniska Högskola; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Authentication solutions are designed to stop unauthorized users from getting access to a secured system. However, each time an authentication process occur an authorized user needs to wait in expectation of approved access. This effort can be perceived as either a positive or negative experience.

3. 17. Web Authentication using Third-Parties in Untrusted Environments

   Författare :Anna Vapen; Nahid Shahmehri; Niklas Carlsson; Steve Furnell; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : With the increasing personalization of the Web, many websites allow users to create their own personal accounts. This has resulted in Web users often having many accounts on different websites, to which they need to authenticate in order to gain access. LÄS MER

4. 18. Toward Adjustable Lightweight Authentication for Network Access Control

   Författare :Henric Johnson; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : The increasing use of Internet access networks raises the demand for secure and reliable communication for both users and businesses. Traditionally, the aim has been to provide the strongest possible security. LÄS MER

5. 19. Query authentication and data confidentiality in wireless sensor networks

   Författare :Ioana Rodhe; Christian Rohner; Per Gunningberg; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datavetenskap med inriktning mot datorkommunikation; Computer Science with specialization in Computer Communication;

   Sammanfattning : In this thesis we consider different aspects of security in sensor networks, in particular query authentication and confidential data aggregation. Authenticating the queries is important so attackers cannot modify existing queries because this would lead to wrong readings; or insert new queries into the network because this would lead to waste of energy.

7. 20. Lip-motion and speech biometrics in person recognition

   Författare :Maycel Isaac Faraj; Högskolan i Halmstad; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Audio-visual recognition; biometrics; Biometric recognition; Speaker verification; Speaker authentication; Person identification; Lip movements; Motion; Structure tensor; Orientation; Optical flow; Hidden Markov Model; Gaussian Markov Model; Lip-motion; Image analysis; Bildanalys;

   Sammanfattning : Biometric identification techniques are frequently used to improve security, e.g. in financial transactions, computer networks and secure critical locations. The purpose of biometric authentication systems is to verify an individual by her biological characteristics including those generating characterisitic behaviour. LÄS MER
