  2. 1. Secure emergency communications of emergency responders : a case study of Kemi municipality in Finland

    Author : Heidi Hartikainen; Erik Borglund; Luleå tekniska universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; emergency management; information security; emergency response; emergency communications; secure communications; Data- och systemvetenskap; Computer and Systems Science;

    Abstract : Emergency response is highly time-critical and information dependent: every moment counts and organizations need to access various information that supports their decision making and informs them about the scale and location of the emergency, the damages, and the availability of human and physical resources. This kind information can originate from many different places and the situation can be stressful as there is a need to communicate quickly, reliably and accurately within their own organization, but also inter-organizationally.

  4. 2. Experimental multiuser secure quantum communications

    Author : Jan Bogdanski; Mohamed Bourennane; Nobuyuki Imoto; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Quantum key distribution; multiparty quantum secret sharing; Sagnac interferometer; “plug play” QKD; Passive Optical Network PON ; decoy states; single mode fiber birefringence compensation; quantum bit error rate; visibility; Physics; Fysik; fysik; Physics;

    Abstract : We are currently experiencing a rapid development of quantum information, a new branch of science, being an interdisciplinary of quantum physics, information theory, telecommunications, computer science, and many others. This new science branch was born in the middle of the eighties, developed rapidly during the nineties, and in the current decade has brought a technological breakthrough in creating secure quantum key distribution (QKD), quantum secret sharing, and exciting promises in diverse technological fields.

  7. 5. Secure Tactical Communications for Inter-Organizational Collaboration : The Role of Emerging Information and Communications Technology, Privacy Issues, and Cyber Threats on the Digital Battlefield

    Author : Johan Sigholm; Martin Norsell; Anne Persson; Gurpreet Dhillon; Högskolan i Skövde; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Försvarssystem; Systems science for defence and security; Information Systems; Informationssystem IS ;

    Abstract : The development within the area of information and communications technology (ICT) has been rapid during the last couple of decades. Advancements in mobile technology, such as smartphones and other portable devices with embedded sensors, rapid expansion of communications infrastructure, and increased spectrum utilization, has had a major impact on civilian society, but increasingly also on professional organizations such as the Swedish Armed Forces.
