1. Some results on fast correlation attacks
Sammanfattning : This thesis presents new results on fast correlation attacks on stream ciphers. In particular, fast correlation attacks on stream ciphers containing linear shift registers with an arbitrary number of taps, are considered. A general introduction to stream ciphers and correlation attacks is given. LÄS MER
2. Some Results on Distinguishing Attacks on Stream Ciphers
Sammanfattning : Stream ciphers are cryptographic primitives that are used to ensure the privacy of a message that is sent over a digital communication channel. In this thesis we will present new cryptanalytic results for several stream ciphers. LÄS MER
3. Acute intermittent porphyria : studies of chronic disease, recombinant enzyme therapy and 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. Ligand Dependent Regioselectivity in Palladium Mediated Allylic Alkylation
Sammanfattning : In this thesis, different aspects on ligand dependent regioselectivity in palladium mediated allylic alkylation have been studied. It is believed that the regioselectivity is a result of nucleophilic attack trans to phosphorous when applying ligands wih different donor atoms. LÄS MER
5. Carbon castles vs. beetle-fungus armies : phenology of the spruce bark beetle and Norway spruce resistance in times of climate change
Sammanfattning : In recent years, carbon sequestration in European forests has decreased due to extensive droughts and bark beetle outbreaks brought on by climate change. The Eurasian spruce bark beetle (Ips typographus (L.)) is a natural disturbance agent in forests where Norway spruce (Picea abies (Karst)) is dominant. LÄS MER
