  1. 16. Aspects of Secure and Efficient Streaming and Collaboration

    Författare :Gunnar Kreitz; Johan Håstad; Shai Halevi; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datalogi;

    Sammanfattning : Research within the area of cryptography constitutes the core of this the- sis. In addition to cryptography, we also present results in peer-assisted streaming and web security. We present results on two specific cryptographic problems: broadcast encryption and secure multi-party computation. LÄS MER

  2. 17. Automated Deductive Verification of Safety-Critical Embedded Software

    Författare :Christian Lidström; Dilian Gurov; Musard Balliu; Bernhard Beckert; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; software sontracts; contract-based design; formal verification; deductive verification; contract inference; program instrumentation; embedded software; embedded systems; Frama-C; Datalogi; Computer Science;

    Sammanfattning : Embedded systems are everywhere in society, and in many industries, such as the automotive industry, embedded systems are safety-critical. Embedded systems are today also increasingly controlled by software, with advances in, for example, autonomous driving. LÄS MER

    Författare :Andreas Lindner; Roberto Guanciale; Mads Dam; Tamara Rezk; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Binary Code; Binary Analysis; Formal Verification; Model-Based Testing; Theorem Proving; HOL4; Intermediate Language; Instruction Set Architectures; ISA; Observational Models; Symbolic Execution; Weakest-Precondition; Execution Time Analysis; binärkod; binärkodsanalys; formell verifiering; modellbaserad testning; satsbevisning; HOL4; mellankod; instruktionsuppsättningar; ISA; observationsmodeller; symbolisk exekvering; minst restriktiva villkoret; analys av övre tidsgräns; Datalogi; Computer Science;

    Sammanfattning : With the increasing ubiquity of computing devices, their correct and secure operation is of growing importance. In particular, critical components that provide core functionalities or process sensitive data have to operate as intended. LÄS MER

  4. 19. On Complexity Measures in Polynomial Calculus

    Författare :Mladen Mikša; Jakob Nordström; Jacobo Torán; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Science; Datalogi;

    Sammanfattning : Proof complexity is the study of different resources that a proof needs in different proof systems for propositional logic. This line of inquiry relates to the fundamental questions in theoretical computer science, as lower bounds on proof size for an arbitrary proof system would separate P from NP. LÄS MER

  5. 20. Secure System Virtualization : End-to-End Verification of Memory Isolation

    Författare :Hamed Nemati; Mads Dam; Gustavo Betarte; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Platform Security; Hypervisor; Formal Verification; Theorem Proving; HOL4; Cache attack; Security Monitor; Information Flow; Computer Science; Datalogi;

    Sammanfattning : Over the last years, security-kernels have played a promising role in reshaping the landscape of platform security on embedded devices. Security-kernels, such as separation kernels, enable constructing high-assurance mixed-criticality execution platforms on a small TCB, which enforces isolation between components. LÄS MER
