1. Partitioning oracle attacks against variants of AES-GCM and ChaCha20-Poly1305
University essay from Linnéuniversitetet/Institutionen för matematik (MA)Abstract : We investigate so-called partitioning oracle attacks against AES-GCM and ChaCha20-Poly1305 along with some improvements. Such attacks against these two cryptosystems are efficient because they can be reduced to solving linear systems of equations over finite fields. READ MORE

2. Compressed sensing for error correction on real-valued vectors
University essay from Linnéuniversitetet/Institutionen för matematik (MA)Abstract : Compressed sensing (CS) is a relatively new branch of mathematics with very interesting applications in signal processing, statistics and computer science. This thesis presents some theory of compressed sensing, which allows us to recover (high-dimensional) sparse vectors from (low-dimensional) compressed measurements by solving the L1-minimization problem.

3. Improved lifetime of a rubber spring in an articulated hauler through product development
University essay from Linnéuniversitetet/Institutionen för maskinteknik (MT)Abstract : Dampening systems are important in heavy vehicles utilized in rough terrains, with purpose to reduce shocks and vibrations with negative influences on the vehicle and, more importantly, on the operator of the vehicle. During the years the heavy vehicles require sturdier construction parts, due to demands on higher load capacity, where the easy solution to scale up the construction parts is not always applicable for dampening systems with nonlinear behavior.
