  1. 16. Deep Learning Based Side-Channel Analysis of AES Based on Far Field Electromagnetic Radiation

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

    Författare :Ruize Wang; [2020]
    Nyckelord :Side-Channel Attacks; EM; Far-Field; Deep Learning;

    Sammanfattning : Advanced Encryption Standard (AES) is a widely accepted encryption algorithm used in Internet-of-Things (IoT) devices such as Bluetooth devices. Although the implementation of AES is complicated enough, attackers can still acquire the cryptographic information generated from the AES execution to perform Side-Channel Attack (SCA). LÄS MER

  3. 17. Design of a Size Reduced Antenna Array for Angle of Arrival (AoA) Estimation for BLE 5.1

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Felix Långberg; Jonas Thurborg; [2020]
    Nyckelord :Antenna; Array; Bluetooth; 5.1; Angle of arrival; optimization; Technology and Engineering;

    Sammanfattning : Bluetooth low energy (BLE) 5.1 allows for Angle of Arrival(AoA) measurements which in turn requires antenna arrays to be used. These arrays must be low power which results in that an efficient switching pattern is applied and for greater field of view good omnidirectivity is necessary. LÄS MER

  4. 18. Improved Accuracy for Indoor Positioning with Bluetooth 5.1: From Theory to Measurements

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Victor Sesma Santos; Victor Egorov; [2020]
    Nyckelord :Technology and Engineering;

    Sammanfattning : In this thesis we are evaluating Bluetooth Low Energy (BLE) v5.1 in combination with Direction Of Arrival (DOA) algorithms and receiving antenna arrays for indoor positioning systems. The thesis is divided in two parts. The first part is the core of the thesis and is composed by the evaluation of DOA algorithms in a direction finding system. LÄS MER

  5. 19. Link performance measurement and improvement using Bluetooth mesh network

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Durgaprasad Srinivasa; Manjunath Harshavardhan Manjunath Harshavardhan; [2020]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Bluetooth is a short-range technology, it helps with wireless communication between many electronic devices. Bluetooth low energy (BLE) is the advanced version of Bluetooth which uses low energy compared to the standard Bluetooth. Bluetooth mesh technology play a crucial role in the Internet of things (IoT). LÄS MER

  7. 20. A Cost-Efficient Bluetooth Low Energy Based Indoor Positioning System for IoT Applications

    Master-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Sanjana Vupparige Vijaykumar; [2019]
    Nyckelord :Indoor positioning system; Internet of Things; Bluetooth Low Energy technology; RSSI; fingerprinting; multilateration.;

    Sammanfattning : The indoor positioning system is a series of networking systems used to monitor/locate objects at indoor area as opposed that of GPS which does the same at outdoor. The increase in the popularity of the Internet of Things made the demand for Bluetooth Low Energy technology more and more essential due to their compatibility in the smartphones which makes it to access easier.
