  • Radix-4 ASIC design of a scalable Montgomery modular multiplier using encoding techniques

    Creator:
    Tawalbeh, Lo'ai
    Abstract:
    Modular arithmetic operations (i.e., inversion, multiplication and exponentiation) are used in several cryptography applications, such as decipherment operation of RSA algorithm, Diffie-Hellman key exchange algorithm, elliptic curve cryptography, and the Digital Signature Standard including the Elliptic Curve Digital Signature Algorithm. The most important of these arithmetic operations is the modular...

  • 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...

  • Efficient key management protocols for mobile ad hoc networks

    Creator:
    Erdem, Özkan M.
    Abstract:
    In this thesis, novel solutions are proposed for key management issues in mobile ad hoc networks. Presented Hierarchical Binary Tree (HBT) based model is distributed, self-organizing, scalable and does not employ online key distribution authority or group manager. Two different group authentication and group key establishment protocols are proposed for...

  • Hardware realization of OCB mode for efficient authenticated encryption

    Creator:
    Al Faresi, Ahmed
    Abstract:
    Authenticated-Encryption modes of operation have recently received great atten- tion amongst researchers. Such modes of operation provide both privacy and authentic- ity. A proposed mode in this category is the Offset Codebook mode (OCB) by Rogaway et al. This mode shows great substantial advantages over conventional modes. In the past...

  • 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...

  • 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...

  • Side channel attack resistant elliptic curves cryptosystem on multi-cores for power efficiency

    Creator:
    Yoo, Jaewon
    Abstract:
    The Advent of multi-cores allows programs to be executed much faster than before. Cryptoalgorithms use long-bit words thus parallelizing these operations on multi-cores will achieve significant performance improvement. However, not all long-bit word operations in cryptosystems are suitable for parallel execution on multi-cores. In particular, long-bit words used in Elliptic...

    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...
