1. 1. Topics in Authentication Theory

   Författare :Christian Gehrmann; Institutionen för elektro- och informationsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polynomial evaluation; anonymous secret sharing; multiround authentication; group authentication; threshold cryptography; MAC; secret sharing; cryptology; Authentication; authentication codes; Systems engineering; computer technology; Data- och systemvetenskap;

   Sammanfattning : Authentication theory deals with problems connected with the protection of information sent over insecure channels. This thesis concerns different problems in authentication theory. In particular, we consider unconditionally secure authentication, i.e. LÄS MER

3. 2. Contributions to Web Authentication for Untrusted Computers

   Författare :Anna Vapen; Nahid Shahmehri; Simone Fischer-Hübner; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Authentication; security levels; identity management; 2-clickAuth; information security; Computer science; Datalogi;

   Sammanfattning : Authentication methods offer varying levels of security. Methods with one-time credentials generated by dedicated hardware tokens can reach a high level of security, whereas password-based authentication methods have a low level of security since passwords can be eavesdropped and stolen by an attacker.

4. 3. 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.

5. 4. Be More and be Merry: Enhancing Data and User Authentication in Collaborative Settings

   Författare :Elena Pagnin; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Homomorphic Signatures; Server-Aided Verification; Distance-Bounding Authentication Protocols; Verifiable Com- putation; Biometric Authentication.;

   Sammanfattning : Cryptography is the science and art of keeping information secret to un-intended parties. But, how can we determine who is an intended party and who is not? Authentication is the branch of cryptography that aims at confirming the source of data or at proving the identity of a person. This Ph.D. LÄS MER

7. 5. On Some Symmetric Lightweight Cryptographic Designs

   Författare :Martin Ågren; Institutionen för elektro- och informationsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lightweight cryptography; integrity; authentication; symmetric cryptography; stream ciphers; block ciphers; Grain-128a; BEAN; KTANTAN; textsc{PRINTcipher}; FCSR combiner; related-key attack; linear cryptanalysis; linear correlations; invariant subspace attack.;

   Sammanfattning : This dissertation presents cryptanalysis of several symmetric lightweight primitives, both stream ciphers and block ciphers. Further, some aspects of authentication in combination with a keystream generator is investigated, and a new member of the Grain family of stream ciphers, Grain-128a, with built-in support for authentication is presented.
