  1. 16. Topics in Authentication Theory

    Författare :Christian Gehrmann; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polynomial evaluation; anonymous secret sharing; multiround authentication; group authentication; threshold cryptography; MAC; secret sharing; cryptology; Authentication; authentication codes; Systems engineering; computer technology; Data- och systemvetenskap;

    Sammanfattning : Authentication theory deals with problems connected with the protection of information sent over insecure channels. This thesis concerns different problems in authentication theory. In particular, we consider unconditionally secure authentication, i.e. LÄS MER

  3. 17. The secret life of nuclear IGF-1R : functions beyond traditional signaling pathways

    Författare :Dudi Warsito; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The implications of IGF-1R in normal development and disease are well established. IGF-1R plays pivotal roles in cell proliferation and cell survival and aberrant activation result in tumorigenesis and cancer progression. LÄS MER

  4. 18. Performance Improvements for the Rasterization Pipeline

    Författare :Jon Hasselgren; Institutionen för datavetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Rasterization; Computer Graphics; Graphics Hardware;

    Sammanfattning : Performance improvements are always needed in computer graphics. Better performance frees up computational resources which can be used to increase the level of realism in the rendered images. Despite a very rapid development of graphics hardware, we are still far from the point where photo-realistic rendering can be done in real time. LÄS MER

  5. 19. Two topics in cryptography : lattice problems and the security of protocols

    Författare :Mårten Trolin; Johan Håstad; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Datalogi; Datalogi; Computer science; Datalogi;

    Sammanfattning : In this thesis we present new results in two areas – cryptographic protocols and lattice problems. • We present a new protocol for electronic cash which is designed to function on hardware with limited computing power. The scheme has provable security properties and low computational requirements, but it still gives a fair amount of privacy. LÄS MER

  7. 20. Outsourcing Computations to a Cloud That You Don't Trust

    Författare :Georgia Tsaloli; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; differential privacy; function secret sharing; homomorphic secret sharing; verifiable computation; privacy-preservation; public verifiability;

    Sammanfattning : In many application scenarios, data need to be collected, stored and processed. Often sensitive data are collected from IoT devices, which are constrained regarding their resources, and, thus, remote, untrusted cloud servers are required to perform the computations. LÄS MER
