  1. 1. Dynamic enforcement of decentralized security policies

    Author : Jonas Magazinius; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dynamic; enforcement; security; policies; decentralized;

    Abstract : This thesis explores defining security policies in a decentralized setting and dynamic methods of enforcing such policies. In a decentralized setting, principals are free to trust or distrust other principals. The key challenge is to provide possibilities for expressing and enforcing expressive decentralized policies.

  2. 2. Decentralized Application Security

    Author : Per Hallgren; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Decentralization; Homomorphic Encryption; Location-Based Services; Privacy;

    Abstract : On the internet today, everything is centralized. For most people, a single commercial entity owns the power to disclose all their personal emails. Most commonly your emails are only disclosed to you and your correspondent, but the power to choose who sees these emails is in fact not yours. READ MORE

  3. 3. Decentralized Control of Networked Systems Information Asymmetries and Limitations

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Farhad Farokhi; KTH.; KTH.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Networked Control Systems; Decentralized Control; Limited Model Information; Transportation Systems; Sensor Scheduling;

    Abstract : Designing local controllers for networked systems is challenging, because in these systems each local controller can often access only part of the overall information on system parameters and sensor measurements. Traditional control design cannot be easily applied due to the unconventional information patterns, communication network imperfections, and design procedure complexities. READ MORE

  4. 4. Small-Scale Decentralized Energy Systems optimization and performance analysis

    University dissertation from KTH Royal Institute of Technology

    Author : Sara Ghaem Sigarchian; KTH.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Small-scale polygeneration energy systems; techno-economic optimization; renewable energy; operating strategy; particle swarm optimization; optimization algorithm; decentralized energy system;

    Abstract : Small-scale polygeneration energy systems, providing multiple energy services, such as heating, electricity, cooling, and clean water, using multiple energy sources (renewable and non-renewable) are considered an important component in the energy transition movement. Exploiting locally available energy sources and providing energy services close to the end users have potential environmental, economic, and societal benefits. READ MORE

  5. 5. Decentralized Modular Router Architectures

    University dissertation from Stockholm : KTH

    Author : Markus Hidell; KTH.; [2006]
