  2. 6. Cooperation for Secrecy in Wireless Networks

    Author : Frederic Gabry; Mikael Skoglund; Eduard A. Jorswieck; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The growth of wireless networks has been considerable over the last decades. Due to the broadcast nature of these networks, security issues have taken a critical role in today’s communications. READ MORE

  4. 7. Coding and Transmission Strategies for Secrecy

    Author : Mattias Andersson; Mikael Skoglund; Matthieu Bloch; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Abstract : In this thesis we consider several problems relating to information theoretic security. The wiretap channel is the simplest information theoretic setting which takes security into account, and in the first chapters of the thesis we design some practical coding schemes for this channel model.

  5. 8. Secrecy for mobile implementations of security protocols

    Author : Pablo Giambiagi; KTH; []
    Keywords : ;

    Abstract : Mobile code technology offers interesting possibilities tothe practitioner, but also raises strong concerns aboutsecurity. One aspect of security is secrecy, the preservationof confidential information. READ MORE

  6. 9. Interference Alignment with Imperfect Channel Knowledge and Secrecy Constraints

    Author : Zhao Wang; Mikael Skoglund; Ming Xiao; Sheng Yang; KTH; []
    Keywords : Informations- och kommunikationsteknik; Information and Communication Technology;

    Abstract : In this thesis, the degrees of freedom (DOF) of wireless networks are studied with imperfect channel state information at transmitters (CSIT) and/or secrecy constraints. Different interference alignment schemes are proposed to establish the DOF lower bound for a variety of wireless networks. READ MORE

  7. 10. Performance Analysis in Wireless HetNets: Traffic, Energy, and Secrecy Considerations

    Author : Georgios Smpokos; Nikolaos Pappas; Vangelis Angelakis; Qinghua Wang; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : To this day, most of the communication networks are characterized by a "monolithic" operating approach. Network elements are configured and operate without any reconfiguration for long time periods. Softwarization, whereby dedicated elements are being replaced by more general-purpose devices, has been lately challenging this existing approach. READ MORE
