  1. 1. Dynamic enforcement of decentralized security policies

    Författare :Jonas Magazinius; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dynamic; enforcement; security; policies; decentralized;

    Sammanfattning : 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.

  7. 5. Shifting Dangers in the Shape of Threats and Risks : The Discourse of Swedish Security Policy, 1979-2020

    Författare :Jonatan Stiglund; Mark Rhinard; Håkan Edström; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Threat s ; risk s ; logic s of security; security constructions; discourse s ; Sweden; security policy; accountability; power; internationella relationer; International Relations;

    Sammanfattning : Modern societies have become increasingly preoccupied with the identification and preemption of risk, represented as future possibilities of harm. The study demonstrates how the concept of risk has influenced the contemporary Swedish security discourse and what it means to construct security following a risk logic. LÄS MER
