  1. 11. 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

  3. 12. Bringing Visibility in the Clouds : using Security, Transparency and Assurance Services

    Författare :Mudassar Aslam; Mats Björkman; Christian Gehrmann; Chris Mitchell; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Cloud Security; Trusted Computing; Trustworthy Clouds; Cloud Audits; Security Automation; SCAP; Virtual Machine; Computer Science; datavetenskap;

    Sammanfattning : The evolution of cloud computing allows the provisioning of IT resources over the Internet and promises many benefits for both - the service users and providers. Despite various benefits offered by cloud based services, many users hesitate in moving their IT systems to the cloud mainly due to many new security problems introduced by cloud environments.

  4. 13. Some Problems in Quantified Security

    Författare :Vilhelm Verendel; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; computer security; quantified risk; quantified security; risk behavior; operational risk; security metrics; information security; survey; quantitative models; decision-making; risk perception;

    Sammanfattning : This thesis contains work related to quantitative representation and analysis of computer and information security. The ability to accurately describe security using quantitative methods could offer better control and evaluation of security in operational settings. LÄS MER

  5. 14. Observations on Operating System Security Vulnerabilities

    Författare :Stefan Lindskog; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; computer security; operating system; vulnerability; intrusion; experiment; modeling; analysis; Datavetenskap; Computer Science;

    Sammanfattning : This thesis presents research on computer security vulnerabilities in general-purpose operating systems. The objective is to investigate intrusions in such systems in order to find and model the underlying generic weaknesses, i.e., weaknesses that would be applicable to many different systems. LÄS MER

  7. 15. Techniques for Improving Intrusion Detection

    Författare :Magnus Almgren; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; IDS cooperation; IDS response; application-integrated IDS; computer security; intrusion detection; alert reasoning;

    Sammanfattning : Intrusion detection systems (IDSs) have become a vital part of operational computer security. They are the last line of defense against malicious hackers and help to detect ongoing attacks and mitigate their damage. LÄS MER
