  2. 1. Securing Communication in IP-Connected Industrial Wireless Sensor Networks

    Author : Shahid Raza; Mats Björkman; Ben Smeets; Mälardalens högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Wireless Sensor Networks; Security; 6LoWPAN; IPsec; WirelessHART; Computer science; Datavetenskap; Computer Science; datavetenskap;

    Abstract : With the advent of wireless sensor networks (WSN) and success of wirelesscommunication in the local and personal area networks such asWi-Fi and Bluetoothmore serious efforts to apply standard wireless communication in sensitiveindustrial networks were initiated. This effort resulted in the standardizationof WirelessHART. READ MORE

  4. 2. Secure and Privacy-Aware Data Collection in Wireless Sensor Networks

    Author : Ioana Rodhe; Christian Rohner; Per Gunningberg; Roberto Di Pietro; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Secure Data Collection; Key Distribution; Location Privacy; Quality of Information; Wireless Sensor Networks; Datavetenskap med inriktning mot datorkommunikation; Computer Science with specialization in Computer Communication;

    Abstract : A wireless sensor network is a collection of numerous sensors distributed on an area of interest to collect and process data from the environment. One particular threat in wireless sensor networks is node compromise attacks, that is, attacks where the adversary gets physical access to a node and to the programs and keying material stored on it.

  5. 3. Security and Self-stabilization in Sensor Network Services

    Author : Andreas Larsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Clock-synchronization; Secure and Resilient Computer Systems; Ad-hoc Networks; Self-Stabilization; Sensor-Network Systems; Clustering;

    Abstract : Wireless sensor networks consist of small sensor nodes that monitor their environment and that together can cover vast geographical regions. It is a promising field with many possible applications in different application areas. Typically the nodes do not have any preexisting information about the network topology when deployed.

  6. 4. Enabling Scalable Security in Internet of Things

    Author : Zhitao He; Thiemo Voigt; Shahid Raza; Per Gunningberg; Mário Alves; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Internet of Things; Wireless Sensor Networks; Radio Interference; Denial-of-service Attacks; Public Key Infrastructure; Electrical Engineering with Specialisation in Networked Embedded Systems; Elektroteknik med inriktning mot nätverksbaserade inbyggda system;

    Abstract : The popular notion of Internet of Things (IoT) implies two salient features: 1. a diversity of small things, i.e., constrained devices; 2. READ MORE

  7. 5. Query authentication and data confidentiality in wireless sensor networks

    Author : Ioana Rodhe; Christian Rohner; Per Gunningberg; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datavetenskap med inriktning mot datorkommunikation; Computer Science with specialization in Computer Communication;

    Abstract : In this thesis we consider different aspects of security in sensor networks, in particular query authentication and confidential data aggregation. Authenticating the queries is important so attackers cannot modify existing queries because this would lead to wrong readings; or insert new queries into the network because this would lead to waste of energy.
