1. 1. Profile Based Access Control Model Using JSON Web Tokens

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

   Författare :Mustafa Albayati; Aslan Murjan; [2023]
   Nyckelord :access control; profiles; IoT; device; OpenIDC; Technology and Engineering;

   Sammanfattning : Currently at Axis, a local role-based access control system is used in devices, which forces the user credentials to be directly installed on the individual devices and the limited selection of roles does not allow for fine-grained access rights. This creates an administrative nightmare in a large scale network and leads to elevated privileges. LÄS MER

3. 2. Privacy Preserving Biometric Multi-factor Authentication

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

   Författare :Emil Gedenryd; [2023]
   Nyckelord :Fully Homomorphic Encryption; Machine Learning; Biometric Authentication; Technology and Engineering;

   Sammanfattning : This thesis investigates the viability of using Fully Homomorphic Encryption and Machine Learning to construct a privacy-preserving biometric multi-factor authentication system. The system is based on the architecture described as ”Model K - Store distributed, compare distributed” in ISO/IEC 24745:2022 and uses the Torus Fully Homomorphic Encryption scheme proposed by Chillotti et al.
