3. 42. Acute intermittent porphyria : studies of chronic disease, recombinant enzyme therapy and late complications

   Författare :Eliane Sardh; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Acute intermittent porphria; porphobilinogen; 5-aminolevulinic acid; porphobilinogen deaminase; enzyme therapy; acute porphyria attack; chronic active disease; late complications;

   Sammanfattning : This thesis comprise five studies on patients with acute intermittent porphyria (AIP) observed under different clinical conditions associated with the disorder. They have generally been monitored at the porphyria out-patient clinic in Stockholm South Hospital, and were biochemically monitored at Porphyria Centre Sweden. LÄS MER

4. 43. On LFSR based Stream Ciphers - analysis and design

   Författare :Patrik Ekdahl; Institutionen för elektro- och informationsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; self-shrinking generator; shrinking generator; E0; A5; sober; stream cipher; LFSR; snow; Informatics; systems theory; Informatik; systemteori;

   Sammanfattning : Stream ciphers are cryptographic primitives used to ensure privacy in digital communication. In this thesis we focus on stream ciphers built using Linear Feedback Shift Registers (LFSRs). Several different stream ciphers are analysed and new attacks are presented. In addition, two new stream ciphers are presented, both based on the same design. LÄS MER

5. 44. Tuning of Anomaly Detectors in the Presence of Sensor Attacks

   Författare :David Umsonst; Henrik Sandberg; Justin Ruths; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Critical infrastructures, such as the power grid and water distribution networks, are the backbone of our modern society. With the integration of computational devices and communication networks in critical infrastructures, they have become more efficient, but also more vulnerable to cyberattacks. LÄS MER

7. 45. On the Design and Analysis of Stream Ciphers

   Författare :Martin Hell; Institutionen för elektro- och informationsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; weak feedback polynomials; bit-search generator; self-shrinking generator; Achterbahn; Pomaranch; Grain-128; Grain; stream ciphers; cryptography; cryptanalysis; Informatics; systems theory; Informatik; systemteori;

   Sammanfattning : This thesis presents new cryptanalysis results for several different stream cipher constructions. In addition, it also presents two new stream ciphers, both based on the same design principle. The first attack is a general attack targeting a nonlinear combiner. LÄS MER
