  1. 1. Adversarial robustness of STDP-trained spiking neural networks

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Karl Lindblad; Axel Nilsson; [2023]
    Nyckelord :;

    Sammanfattning : Adversarial attacks on machine learning models are designed to elicit the wrong behavior from the model. One such attack on image classifiers are maliciously crafted inputs that, to the human eye, look untampered with but have been carefully altered to cause misclassification. LÄS MER

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

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

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

    Sammanfattning : 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. LÄS MER

  3. 3. Clueless: A Tool Characterising Values Leaking as Addresses : Clueless: A Tool Characterising Values Leaking as Addresses

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Xiaoyue Chen; [2022]
    Nyckelord :;

    Sammanfattning : A fundamental programming feature that allows Spectre to effortlessly leak the value of secrets via cache side channels is the transformation of data values into addresses. Consider forexample sorting, hashing, or many other algorithms that create addresses based on datavalues. LÄS MER

  4. 4. Tor och webbplatsorakel : Konstruktion och utvärdering av webbplatsorakel från DNS-tidtagning i Tor-nätverket.

    Kandidat-uppsats, Karlstads universitet

    Författare :Oscar Andersson; [2021]
    Nyckelord :Tor; The Tor Project; The Onion Router; Website Oracle; Attack; Penetration Testing; Network; Security; Side channel attack; DNS; Timing; Darknet; Dark net; Tor; Nätverksteknik; Attack; Webbplatsorakel; Sidokanalsattack; Penetrationstest; Datasäkerhet; Informationssäkerhet; DNS; The Tor Project; Darknet; Dark net;

    Sammanfattning : This paper discsusses the question: is website oracles in Tor from timing DNS something we have to worry about? This paper builds apon the findings done by Rasmus Dahlberg and Tobias Pulls in thier paper Website Fingerprinting with Website Oracles. A website oracle is a side channel attack that answers the predicate: has this website been visited before? The website oracle is constructed and test are carried out, with great outcome, resulting in that website oracles from timing DNS is not an attack that puts individuals using Tor at risk, but certanly challanges the idea of an anonymity network when such a lot of data can be derived from DNS.

  5. 5. Laget före jaget? : En kvalitativ studie om hur svenska sportorganisationer kommunicerar under en spelares individuella kris

    Kandidat-uppsats, Karlstads universitet/Avdelningen för medie- och kommunikationsvetenskap

    Författare :Albin Bjerkland; Benjamin Edman; [2018]
    Nyckelord :Image repair theory; rhetoric; crisis communication; sports organization; response; Image repair theory; retorik; kriskommunikation; sportorganisation; responsstrategi;

    Sammanfattning : Idrottsskandaler blir ofta uppmärksammade i nyhetsmedier och aktörerna i krisen behöver därför uttala sig offentligt. Denna studie undersöker hur svenska sportorganisationer, Malmö FF, IF Björklöven, Gefle IF och Pixbo Wallenstam, hanterar en kris som uppstått från ett individuellt övertramp. LÄS MER
