  1. 1. Symmetry Breaking Ordering Constraints

    Detta är en avhandling från Uppsala : Data- och systemvetenskap

    Författare :Zeynep Kiziltan; Andreas Hamfelt; Toby Walsh; Pedro Meseguer; [2004]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Datavetenskap; Constraint satisfaction; constraint programming; modelling; symmetry breaking; global constraints; Datavetenskap; TECHNOLOGY Information technology Computer science; TEKNIKVETENSKAP Informationsteknik Datavetenskap;

    Sammanfattning : Many problems in business, industry, and academia can be modelled as constraint programs consisting of matrices of decision variables. Such “matrix models” often have symmetry. In particular, they often have row and column symmetry as the rows and columns can freely be permuted without affecting the satisfiability of assignments. LÄS MER

  5. 5. Authentication under Constraints

    Detta är en avhandling från Göteborg : University of Gothenburg

    Författare :Elena Pagnin; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Security.; Distance-Bounding; Privacy; Biometrics; Anonymity; Authentication; Digital Signatures;

    Sammanfattning : Authentication has become a critical step to gain access to services such as on-line banking, e-commerce, transport systems and cars (contact-less keys). In several cases, however, the authentication process has to be performed under challenging conditions. LÄS MER
