  • Secure Instant Messaging : the Jabber protocol

    Creator:
    Almanei, Saleh
    Abstract:
    Instant Messaging (IM) has grown rapidly among network users. It has even become a very important tool for the industry around the world. It is used in scheduling meetings, exchanging business information and clients information, and so on. Instant Messaging has been developed by private sectors or providers such as...

  • A comparative study of AES implementations on ARM processors

    Creator:
    Shamsuddin, Rayees
    Abstract:
    AES (Advanced Encryption Standard), also known as Rijndael, is a symmetric key block cipher adopted as an encryption standard by the US government and used extensively in cryptographic applications worldwide. ARM is the most popular processor core used in embedded applications. This thesis surveys the available public implementations of AES...

  • ECDSA optimizations on an ARM processor for a NIST curve over GF(p)

    Creator:
    Tanik, Haluk Kent
    Abstract:
    The Elliptic Curve Digital Signature Algorithm (ECDSA) is the elliptic curve analog of the Digital Signature Algorithm (DSA) and a federal government approved digital signature method. In this thesis work, software optimization techniques were applied to speed up the ECDSA for a particular NTST curve over GF(p). The Montgomery multiplication...

  • High-speed algorithms & architectures for number-theoretic cryptosystems

    Creator:
    Acar, Tolga
    Abstract:
    Computer and network security systems rely on the privacy and authenticity of information, which requires implementation of cryptographic functions. Software implementations of these functions are often desired because of their flexibility and cost effectiveness. In this study, we concentrate on developing high-speed and area-efficient modular multiplication and exponentiation algorithms for...

  • ECDSA optimizations on ARM processor for a NIST curve over GF(2m)

    Creator:
    Turan, Eda
    Abstract:
    The Elliptic Curve Digital Signature Algorithm (ECDSA) is one of the most popular algorithms to digitally sign streams or blocks of data. In this thesis we concentrate on porting and optimizing the ECDSA on the ARM7 processor for a particular NIST curve over GF(2[superscript m]). The selected curve is a...

  • Cryptanalysis and enhancement of authentication protocols

    Creator:
    Kim, Minho
    Abstract:
    Authentication protocols play important roles in network security. A variety of authentication protocols ranging from complex public-key cryptosystems to simple password-based authentication schemes have been proposed. However, currently there is no fully secure authentication scheme that can resist all known attacks. When a user authentication is performed over an insecure...

  • Implementation aspects of elliptic curve cryptography

    Creator:
    Savaș, Erkay
    Abstract:
    As the information-processing and telecommunications revolutions now underway will continue to change our life styles in the rest of the 21st century, our personal and economic lives rely more and more on our ability to transact over the electronic medium in a secure way. The privacy, authenticity, and integrity of...

  • Fast bit-level, word-level and parallel arithmetic in finite fields for elliptic curve cryptosystems

    Creator:
    Halbutoğulları, Alper
    Abstract:
    Computer and network security has recently become a popular subject due to the explosive growth of the Internet and the migration of commerce practices to the electronic medium. Thus the authenticity and privacy of the information transmitted and the data stored on networked computers is of utmost importance. The deployment...

  • Fast software implementations of block ciphers

    Creator:
    Sessions, Julian Brently
    Abstract:
    Three block ciphers are considered to determine how well they can be implemented on existing superscalar architectures such as the Intel Pentium. An examination of the Pentium architecture suggests that substantial performance increases can be achieved if particular rules are followed. Software libraries are written in high-level C language and...
