  1. 21. Points of High Order on Elliptic Curves : ECDSA

    University essay from Linnéuniversitetet/Institutionen för matematik (MA)

    Author : Behnaz Kouchaki Barzi; [2016]
    Keywords : Digital signature DS. ; Elliptic Curve Digital Signature Algorithm ECDSA ; Elliptic Curve Discrete Logarithm Problem ECDLP ; Baby Step; Giant Step Bs.Gs. ; Pollard’s Rho;

    Abstract : This master thesis is about Elliptic Curve Digital Signature Algorithm or ECDSA and two of the known attacks on this security system. The purpose of this thesis is to find points that are likely to be points of high order on an elliptic curve. If we have a point P of high order and if Q = mP, then we have a large set of possible values of m. READ MORE

  3. 22. Modernizing forms at KTH : Using Digital Signatures

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Pontus Engström; [2016]
    Keywords : Authentication; cryptography; digital signature; digital certificate; X.509; Adobe Acrobat; LDAP; application form; Autentisering; kryptografi; digitala signaturer; digitala certifikat; X.509; Adobe Acrobat; LDAP; ansökningsblankett;

    Abstract : Today both government agencies and companies struggle to keep up with the pace of the continuous change of technology. With all new technology there are benefits, but new problems might also occur. Implementing new technology for certain tasks may increase both efficiency and security, resulting in a more sustainable work environment. READ MORE

  4. 23. On the Applicability of a Cache Side-Channel Attack on ECDSA Signatures : The Flush+Reload attack on the point multiplication in ECDSA signature generation process

    University essay from Blekinge Tekniska Högskola/Institutionen för datalogi och datorsystemteknik

    Author : Sai Prashanth Josyula; [2015]
    Keywords : Digital signatures; Elliptic curve cryptography; GLV method; Side-channel attack;

    Abstract : Context. Digital counterparts of handwritten signatures are known as Digital Signatures. The Elliptic Curve Digital Signature Algorithm (ECDSA) is an Elliptic Curve Cryptography (ECC) primitive, which is used for generating and verifying digital signatures. READ MORE

  5. 24. The Needed Input Data for Accurate On-line Signature Verification : The relevance of pressure and pen inclination for on-line signature verification

    University essay from KTH/Skolan för datavetenskap och kommunikation (CSC)

    Author : Thomas Sjöholm; [2015]
    Keywords : Online signature verification; signature verification; dynamic time warp; pressure sensitivity; susig; Sabanci University Signature Database; signaturverifiering; tryckkänslighet; susig; Sabanci University Signature Database;

    Abstract : Signatures have been used to authenticate documents and transactions for over 1500 years and are still being used today. In this project a method for verifying signatures written on a tablet has been developed and tested in order to test whether pressure information is vital for a well performing on-line signature verification systems.

  6. 25. Building and Tree Parameterization in Partiallyoccluded 2.5D DSM Data

    University essay from Linköpings universitet/Institutionen för systemteknik

    Author : Johan Källström; [2015]
    Keywords : building parameterization; tree identification; Polyhedral Building Models; DSM;

    Abstract : Automatic 3D building reconstruction has been a hot research area; a task which has been done manually even up today. Automating the task of building reconstruction enables more applications where up to date information is of great importance. READ MORE
