    Sammanfattning : 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. LÄS MER

    Sammanfattning : Zigbee network is a popular choice for deploying low power personal area network (LoWPAN). The application areas vary but the most popular are industrial area monitoring and home automation. But Zigbee has been identified to have weak security and is not applicable for industrial implementation. LÄS MER

  7. 5. Encrypting IMSI to improve privacy in 5G Networks

    Uppsats för yrkesexamina på avancerad nivå, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Sammanfattning : Nowadays, the long-term identifier of a user in a mobile network, namely International Mobile Subscriber Identity or IMSI, is transmitted in clear text over the radiointerface. Given that this interface is used as a shared medium, anyone with a radio transceiver and processing software can thus read such identifier. LÄS MER
