  1. 1. Homomorphic encryption

    University essay from KTH/Matematik (Avd.)

    Author : Daniel Sanaee; [2023]
    Keywords : Mathematics; Cryptography; Computer science; Group Theory; Matematik; Kryptografi; Datalogi; Gruppteori;

    Abstract : The problem of constructing a secure encryption scheme that allows for computation on encrypted data was an open problem for more than 30 years. In 2009, Craig Gentry solved the problem, constructing the first fully homomorphic encryption (FHE) scheme. READ MORE

  3. 2. Penetration testing of current smart thermostats : Threat modeling and security evaluation of Shelly TRV and Meross Smart Thermostat

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

    Author : Adam Lindberg; [2023]
    Keywords : IoT penetration testing; Smart thermostat; Ethical hacking; PatrIoT; Cybersecurity; IoT penetrationstestning; Smart termostat; Etisk hackning; PatrIoT; Cybersäkerhet;

    Abstract : As smart homes become increasingly common and concerns over Internet of Things (IoT) security grow, this study delves into the vulnerabilities of smart thermostats. These devices offer convenience but also comes with increased risk of cyber attacks. READ MORE

  4. 3. FFS: A cryptographic cloud-based deniable filesystem through exploitation of online web services : Store your sensitive data in plain sight

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

    Author : Glenn Olsson; [2023]
    Keywords : Filesystem; Fejk FileSystem; Cloud-based filesystem; Steganograhpic filesystem; Filsystem; Fejk FileSystem; Molnbaserat filsystem; Steganografiskt filsystem;

    Abstract : Many Online Web Services (OWSs) today, such as Flickr and Twitter, provide users with the possibility to post images that are stored on the platform for free. This thesis explores creating a cryptographically secure filesystem that stores its data on an online web service by encoding the encrypted data as images. READ MORE

  5. 4. Confidential Federated Learning with Homomorphic Encryption

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

    Author : Zekun Wang; [2023]
    Keywords : Cloud Technology; Confidential Computing; Federated Learning; Homomorphic Encryption; Trusted Execution Environment; Molnteknik; Konfidentiell databehandling; Federerad inlärning; Homomorfisk kryptering; Betrodd körningsmiljö;

    Abstract : Federated Learning (FL), one variant of Machine Learning (ML) technology, has emerged as a prevalent method for multiple parties to collaboratively train ML models in a distributed manner with the help of a central server normally supplied by a Cloud Service Provider (CSP). Nevertheless, many existing vulnerabilities pose a threat to the advantages of FL and cause potential risks to data security and privacy, such as data leakage, misuse of the central server, or the threat of eavesdroppers illicitly seeking sensitive information.

  6. 5. A Side-Channel Attack on Masked and Shuffled Implementations of M-LWE and M-LWR Cryptography : A case study of Kyber and Saber

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

    Author : Linus Backlund; [2023]
    Keywords : Public-key Cryptography; Post-Quantum Cryptography; Kyber; Saber; Side-Channel Attack; Power Analysis; Asymetrisk Kryptering; Kvantsäker Kryptografi; Kyber; Saber; Sidokanalsattack; Effektanalys;

    Abstract : In response to the threat of a future, large-scale, quantum computer, the American National Institute of Standards and Technology (NIST) initiated a competition for designs of quantum-resistant cryptographic primitives. In 2022, the lattice-based Module-Learning With Errors (M-LWE) scheme Kyber emerged as the winner to be standardized. READ MORE
