    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Threat s ; risk s ; logic s of security; security constructions; discourse s ; Sweden; security policy; accountability; power; internationella relationer; International Relations;

    Abstract : 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. READ MORE

  6. 4. Authentication in Quantum Key Distribution : Security Proof and Universal Hash Functions

    Author : Aysajan Abidin; Jan-Åke Larsson; Viiveke Fåk; Robert Forchheimer; Joseph Merrill Renes; Linköpings universitet; []
    Keywords : ;

    Abstract : Quantum Key Distribution (QKD) is a secret key agreement technique that consists of two parts: quantum transmission and measurement on a quantum channel, and classical post-processing on a public communication channel. It enjoys provable unconditional security provided that the public communication channel is immutable. READ MORE

  7. 5. On the security of mix-nets and hierarchical group signatures

    Author : Douglas Wikström; Johan Håstad; Moni Naor; KTH; []

    Abstract : In this thesis we investigate two separate cryptographic notions: mix-nets and hierarchical group signatures. The former notion was introduced by Chaum (1981). The latter notion is introduced in this thesis, but it generalizes the notion of group signatures which was introduced by Chaum and Heyst (1991). READ MORE
