  1. 1. Fundamental Attacks on Ethereum Oracles and How to Prevent Them

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

    Författare :Mikael Jafari; [2023]
    Nyckelord :Blockchain; Attacks; Ethereum; Solana; Corda; Oracle; Blockkedja; Attacker; Ethereum; Solana; Corda; Orakel;

    Sammanfattning : Many applications and protocols on blockchain platforms are reliant on real-world data which exists outside the blockchain, something which is not directly accessible through these platforms. To bridge this gap, blockchain oracles help these applications and protocols by providing them with this data. LÄS MER

  3. 2. Development of chitosan nanocomposite coatings for visible-light photocatalytic antiviral applications

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Michael Neuman; [2023]
    Nyckelord :Biopolymer; Chitosan; Coating; Nanocomposite; Photocatalytic; Zinc oxide; Antimicrobial; Antiviral; Coronavirus COVID-19 ; Biopolymer; Kitosan; Beläggning; Nanokomposit; Fotokatalytisk; Zinkoxid; Antimikrobiell; Antiviral; Coronavirus COVID-19 ;

    Sammanfattning : During the global pandemic of coronavirus, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreak, the world was desperately searching for simpler yet more effective solutions to stop the spread of coronavirus (COVID-19). Since no one was prepared for the fast spread of such a contagious virus, there was a shortage of proper protective solutions to stop the spread. LÄS MER

  4. 3. Threat Analysis of Smart Home Assistants Involving Novel Acoustic Based Attack-Vectors

    Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Författare :Adam Björkman; Max Kardos; [2019]
    Nyckelord :smart home assistants; threats; voice interface; vulnerability; exploit; smarta hemassistenter; hotbild; röstgränssnitt; sammanställning; attack;

    Sammanfattning : Background. Smart home assistants are becoming more common in our homes. Often taking the form of a speaker, these devices enable communication via voice commands. Through this communication channel, users can for example order a pizza, check the weather, or call a taxi. LÄS MER

  5. 4. En jämförelse av skyddsmetoder vid en TCP SYN-Flood-attack

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för informationsteknologi

    Författare :Mattias Bilger; [2018]
    Nyckelord :ddos; syn-flood; syn flood;

    Sammanfattning : Syftet med studien är att undersöka hur processor-, minnesanvändning och responstid påverkas vid en Distributed Denial-of-Service (DDoS) attack av typen TCP SYN-Flood. För att testa detta används metoderna Baseline (utan SYN-Cookies), Mod_Evasive, Suricata samt SYN-Cookies. LÄS MER
