  1. 11. Far Field EM Side-Channel Attack Based on Deep Learning with Automated Hyperparameter Tuning

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

    Författare :Keyi Liu; [2021]
    Nyckelord :Side-Channel Attack; Deep Learning; Far Field EM emission; Auto Hyperparameter Tuning; Auto-Keras; AES; Sidokanalattack; Machine Learning; Multilayer Perceptron; Hyperparameter Tuning; Bayesian Optimization; Auto-Keras; AES;

    Sammanfattning : Side-channel attacks have become a realistic threat to the implementations of cryptographic algorithms. By analyzing the unintentional, side-channel leakage, the attacker is able to recover the secret of the target. Recently, a new type of side-channel leakage has been discovered, called far field EM emissions. LÄS MER

  3. 12. Learned Multi-Sensor Indoor Positioning of Mobile Devices

    Master-uppsats, Lunds universitet/Matematik LTH

  5. 14. Field uniformity and isotropy investigation of Halmstad University's reverberation chamber : In collaboration with Halmstad University and Ericsson AB, Lund

    Magister-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Khaled Ads; [2020]
    Nyckelord :Reverberation chamber;

    Sammanfattning : This thesis is the final module of the Master's program in Electronics Design at Halmstad University. The Master Thesis work is a part of an ongoing development of Halmstad University's reverberation chamber (RC), which is aimed at frequencies in the low GHz range. The development process has been passing in several phases. LÄS MER

  7. 15. Evaluation of Bluetooth 5.1 as an Indoor Positioning System

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Philip Andersson; Linus Persson; [2020]
    Nyckelord :Indoor Positioning System; AoA; RSSI; IMU; Sensor Fusion; Multipath Propagation; Inomhus positioneringssystem; AoA; RSSI; IMU; Sensor Fusion; Flervägsutbredning;

    Sammanfattning : There is a high demand for Indoor Positioning Systems (IPS) due to the wide application possibilities. The main issue for localization by wireless signals in an indoor environment is the multipath propagation problem. Multipath propagation occurs when signals reflects and refract from an object, changing the signals characteristics. LÄS MER
