  • Efficient wireless security protocols based on elliptic curve cryptography

    Creator:
    Aydos, Murat
    Abstract:
    In recent years, the elliptic curve cryptosystems (ECC) have received attention due to their increased security with smaller key size which brings the advantage of less storage area and less bandwidth. Elliptic curve cryptography provides a methodology for obtaining high-speed, efficient, and scalable implementations of network security protocols. In addition...

  • New algorithms and architectures for arithmetic in GF(2[superscript m]) suitable for elliptic curve cryptography

    Creator:
    Rodríguez-Henríquez, Francisco
    Abstract:
    During the last few years we have seen formidable advances in digital and mobile communication technologies such as cordless and cellular telephones, personal communication systems, Internet connection expansion, etc. The vast majority of digital information used in all these applications is stored and also processed within a computer system, and...

  • 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...

  • Symmetric encryption with multiple keys : techniques and applications

    Creator:
    Barlow, Lelia C.
    Abstract:
    Symmetric key block ciphers, such as AES, are well known and frequently used. There are five confidentiality modes of operation that are currently recommended for use with a symmetric key block cipher algorithm: Electronic Codebook (ECB), Cipher Block Chaining (CBC), Cipher Feedback (CFB), Output Feedback (OFB), and Counter (CTR). This...

  • Advances in side-channel cryptanalysis : microarchitectural attacks

    Creator:
    Aciiçmez, Onur
    Abstract:
    Cryptographic devices leak timing and power consumption information that is easily measurable, radiation of various levels, and more. Such devices also have additional inputs, other than plaintext and keys, like voltage, which can be modified to force the device to produce certain faulty outputs that can be used to reveal...

  • Spectral modular arithmetic

    Creator:
    Saldamli, Gökay
    Abstract:
    In many areas of engineering and applied mathematics, spectral methods provide very powerful tools for solving and analyzing problems. For instance, large to extremely large sizes of numbers can efficiently be multiplied by using discrete Fourier transform and convolution property. Such computations are needed when computing π to millions of...

  • Hardware encryption using the MPC180 security co-processor

    Creator:
    Banerjee, Uday
    Abstract:
    Hardware cryptography offers a reliable way to provide security for data that is sent over networks. Security processors have taken the stage in the movement for secure computing. Some of the more prominent security processors belong to the S1 family created by Motorola. The primary goal of this thesis is...

  • Improving the Karatsuba-Ofman multiplication algorithm for special applications

    Creator:
    Erdem, Serdar S.
    Abstract:
    In this thesis, we study the Karatsuba-Ofman Algorithm (KOA), which is a recursive multi-precision multiplication method, and improve it for certain special applications. This thesis is in two parts. In the first part, we derive an efficient algorithm from the KOA to multiply the operands having a precision of 2[superscript...
