  2. 21. Side-Channel Analysis of Post-Quantum Cryptographic Algorithms

    Author : Kalle Ngo; Johnny Öberg; Ingo Sander; Elena Dubrova; Lejla Batina; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Side-channel attack; Post-quantum cryptography; Deep learning; LWE LWR-based KEM; Hardware security; Sidokanalsattack; Postkvantkryptering; Djupinlärning; LWE LWR-baserad KEM; Hårdvarusäkerhet; Informations- och kommunikationsteknik; Information and Communication Technology;

    Abstract : Public key cryptographic schemes used today rely on the intractability of certain mathematical problems that are known to be efficiently solvable with a large-scale quantum computer. To address the need for long-term security, in 2016 NIST started a project for standardizing post-quantum cryptography (PQC) primitives that rely on problems not known to be targets for a quantum computer, such as lattice problems.

  4. 22. All-Digital PWM Transmitters

    Author : Muhammad Touqir Pasha; Ted Johansson; Mark Vesterbacka; Henrik Sjöland; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Electronic devices with wireless connectivity are fast becoming a part of daily life. According to some estimates, in the next five years, 10 billion new devices with internet connectivity would be produced. READ MORE

  5. 23. On Long Proofs of Simple Truths

    Author : Kilian Risse; Per Austrin; Johan Håstad; Jakob Nordström; Benjamin Rossman; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computational Complexity; Lower Bounds; Proof Complexity; Datalogi; Computer Science;

    Abstract : Propositional proof complexity is the study of certificates of infeasibility. In this thesis we consider several proof systems with limited deductive ability and unconditionally show that they require long refutations of the feasibility of certain Boolean formulas. READ MORE

  6. 24. Exploring Alternative Massive MIMO Designs : Superimposed Pilots and Mixed-ADCs

    Author : Daniel Verenzuela; Emil Björnson; Luca Sanguinetti; Michalis Matthaiou; Mohamad Assaad; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The development of information and communication technologies (ICT) provides the means for reaching global connectivity that can help humanity progress and prosper. This comes with high demands on data traffic and number of connected devices which are rapidly growing and need to be met by technological development. READ MORE

  7. 25. Doping of Semiconductor Nanowires

    Author : Jesper Wallentin; Fasta tillståndets fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; metal-organic vapour phase epitaxy; III-V semiconductor materials; nanowires; doping; solar cells; F:2013:Wallentin;

    Abstract : In this thesis, in situ doping during growth of III-V semiconductor nanowires, primarily for photovoltaic applications, is investigated. The nanowires were grown by metalorganic vapor phase epitaxy (MOVPE), with gold seed particles. READ MORE
