  5. 4. Kan symboler överföra mening? : en teoretisk diskussion om kommunikation

    Författare :Stefan Karlsson; Luleå tekniska universitet; []
    Nyckelord :;

    Sammanfattning : This work is divided into two parts - a practical/technical view of communication, followed by a change to a broader view with a theoretical language perspective. The overarching purpose is:To increase the understanding of how meaning is transferred between people through the use of symbols. LÄS MER

  7. 5. Performance Guarantees for Physical Layer Authentication in Mission-Critical Communications

    Författare :Henrik Forssell; Ragnar Thobaben; Stefano Tomasin; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Physical layer authentication; mission-critical communica- tions; worst-case performance; queueing delay performance; stochastic net- work calculus; optimal attack strategies.; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : As the application areas for wireless communications are expanding, we also see new security vulnerabilities arise due to the open nature of the wire- less medium. One particularly challenging problem is how to guarantee the security of emerging mission-critical communications, e.g. LÄS MER
