  1. 1. Information Erasure: An Information-Flow Approach to Semantics and Enforcement

    Författare :Filippo Del Tedesco; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; erasure policies; erasure; information flow; enforcement; Python; security;

    Sammanfattning : Many modern online services require sensitive data to complete their tasks. For this reason, guaranteeing security policies in such services is a major concern. The traditional (and well studied) aspects of security, namely confidentiality, integrity, and availability of data, capture many but not all desirable policies involving sensitive-data. LÄS MER

  2. 2. An Information Flow Approach to Fault-Tolerant Security and Information Erasure

    Författare :Filippo Del Tedesco; [2014]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fault Tolerance; Information Erasure; Information flow security;

    Sammanfattning : Sensitive information is a crucial asset for both individuals and companies. Since it is processed in a largely automated way, it is important that the computational infrastructures are equipped with methods for reasoning about and enforcing security policies. Information flow security has been proposed for this purpose in many contexts. LÄS MER

  4. 4. Learning not to fear : extinction, erasure, and the recovery of fear memories

    Detta är en avhandling från Stockholm : Karolinska Institutet, Dept of Clinical Neuroscience

    Författare :Armita Golkar; Karolinska Institutet.; Karolinska Institutet.; [2013]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Much of the progress in understanding the mechanisms underlying the formation and persistence of fear memories comes from studies of Pavlovian conditioning and extinction. Recently, considerable interest has been turn to strategies that facilitate the development and persistence of extinction. LÄS MER

  5. 5. Investigations of Issues Relevant to the Application of Photon Echoes in Information Technology

    Detta är en avhandling från Division of Atomic Physics, Department of Physics, Faculty of Engineering, LTH, Lund University

    Författare :Ulf Elman; Lunds universitet.; Lund University.; [1998]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nonlinear optics; fibre amplifier; Boolean operation; rare earth metals; Atom- och molekylärfysik; Atomic and molecular physics; optical processing; photon echo; optical storage; Fysicumarkivet A:1998:Elman;

    Sammanfattning : Photon echoes have been studied both experimentally and theoretically, with the main part of the work centred around the concept of using photon echoes for all-optical data storage and processing. The four basic Boolean operators, AND, OR, NOT and XOR have been experimentally demonstrated using photon echoes. LÄS MER
