  • 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...

  • Optimizing the advanced encryption standard on Intel's SIMD architecture

    Creator:
    Godbole, Pankaj
    Abstract:
    The Advanced Encryption Standard (AES) is the new standard for cryptography and has gained wide support as a means to secure digital data. Hence, it is beneficial to develop an implementation of AES that has a high throughput. SIMD technology is very effective in increasing the performance of some cryptographic...

  • A novel unified algorithm and hardware architecture for integrated modular division and multiplication in GF(p) and GF(2[superscript]n) suitable for public-key cryptography

    Creator:
    Tawalbeh, Lo'ai Ali
    Abstract:
    The spread of the internet and communications techniques increases the necessity for security in applications that involves sharing or exchange of secret or private infor- mation. Public-key cryptography is widely used in establishing secure communication channels between the users on the Internet, for E-commerce transactions, and in net- work security...

  • Design of high-speed summing circuitry and comparator for adaptive parallel multi-level decision feedback equalization

    Creator:
    Gao, Hairong
    Abstract:
    Multi-level decision feedback equalization (MDFE) is an effective sampled signal processing technique to remove inter-symbol interference (ISI) from disk read-back signals. Parallelism which doubles the symbol rate can be realized by utilizing the characteristic of channel response and decision feedback equalization algorithm. A mixed-signal IC implementation has been chosen for...
