6. Randomly perturbing the bytecode of white box cryptography implementations in an attempt to mitigate side-channel attacks
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : This study takes one step further towards constructing a tool able to automatically amplify the security on your cryptographic implementations. In white box cryptography the encryption key is hidden inside the encryption algorithm out of plain sight. LÄS MER
7. Airborne Radar Ground Clutter Suppression Using Multitaper Spectrum Estimation : Comparison with Traditional Method
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknikSammanfattning : During processing of data received by an airborne radar one of the issues is that the typical signal echo from the ground produces a large perturbation. Due to this perturbation it can be difficult to detect targets with low velocity or a low signal-to-noise ratio. LÄS MER
8. Block Diagonalization Based Beamforming
Master-uppsats, KTH/Teknisk informationsvetenskapSammanfattning : With increasing mobile penetration multi-user multi-antenna wireless communication systems are needed. This is to ensure higher per-user data rates along with higher system capacities by exploiting the excess degree of freedom due to additional antennas at the receiver with spatial multiplexing.

9. Steady Periodic Water Waves Solutions Using Asymptotic Approach
Master-uppsats, Tillämpad matematikSammanfattning : The aim of this work is to study the relation between two invariants of water flow in a channel of finite depth. The first invariant is the height of the water wave and the second one is the flow force. We restrict ourselves to water waves of small amplitude. LÄS MER
10. Design of a Cylindrical Cavity Resonator for Measurements of Electrical Properties of Dielectric Materials
Master-uppsats, Avdelningen för elektronik, matematik och naturvetenskapSammanfattning : In microwave communications, the main aspects for affecting the dielectric losses in the materials are relating to the dielectric properties and the radiation frequencies. Normally, the different dielectric materials will lead to the different losses and reflections for microwave frequencies. LÄS MER
