1. 1. Determining the Optimal Frequencies for a Duplicated Randomized Clock SCA Countermeasure

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Gabriel Klasson Landin; Truls Julborg; [2023]
   Keywords : Side channel attack; Cryptography; Correlation power analysis; Chipwhisperer; Frequency; Hardware security;

   Abstract : Side-channel attacks pose significant challenges to the security of embedded systems, often allowing attackers to circumvent encryption algorithms in minutes compared to the trillions of years required for brute-force attacks. To mitigate these vulnerabilities, various countermeasures have been developed. READ MORE

3. 2. Automated Generation of EfficientBitslice Implementations forArbitrary Sboxes

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Augustin Bariant; [2023]
   Keywords : Bitslicing; Cryptography; Whitebox; Compilation; Boolean circuits.; Parallélisation au bit; Cryptographie; Boîte blanche; Compilation; Circuits booléens.; Bitslicing; Kryptografi; Vit låda; Kompilering; Booleska kretsar.;

   Abstract : Whitebox cryptography aims at protecting standard cryptographic algorithmsthat execute in attacker-controlled environments. In these, the attacker is ableto read a secret key directly from memory. Common implementations mask alldata at runtime and operate on masked data by using many small precomputedtables. READ MORE

4. 3. Line Distance Protection in Power Grids with Variable Renewable Energy Sources : An Investigation on Time Domain Distance Protection via Parameter Estimation

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Ludvig Ringaby; [2023]
   Keywords : Distance protection; Power system protection; Time domain distance protection; Differential Equation Algorithm; Variable renewable energy; IBR; Distansskydd; Skyddssystem i elkraftsystem; Tidsdomän distansskydd; Differentialekvationsalgoritm; Variabel förnybar energi;

   Abstract : Variable renewable energy sources typically connect to the power grid through power electronic interfaces. Increased use of such sources can cause issues for conventional distance protection. READ MORE

5. 4. Design and Simulation of a 10kW High-Efficiency Dual Active Bridge Converter

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Fan Yang; [2023]
   Keywords : Converter Design; Dual Active Bridge; Single Phase Shift Modulation; Extended Phase Shift Modulation; Efficiency Estimation; Konverterdesign; Dual Active Bridge; Single Fas Shift Modulation; Extended Phase Shift Modulation; Effektivitetsuppskattning;

   Abstract : The EU has proposed an ambitious goal to achieve widespread E-mobility in both the electrical and commercial sectors. To accomplish this, a substantial number of DC fast-charging stations must be built. READ MORE

6. 5. Short-circuit current detection in electric vehicles

   University essay from Uppsala universitet/Signaler och system

   Author : Max Torbjörner; [2022]
   Keywords : Electric vehicles; Current measurement; Short-circuit; BEV Trucks; BJB;

   Abstract : In recent years the vehicle industries have been making much efforts to reduce the environmentalimpact by switching from the traditional combustion engine to electrification with battery driven electricvehicles. Producing electric trucks requires more batteries and operates at a higher voltage and currentthan commercial electric cars. READ MORE
