  • Random access machine in secure multi-party computation

    Creator:
    Hu, Zhangxiang
    Abstract:
    Secure multi-party computation (MPC) is a conceptual framework in cryptography. It allows distrusting parties engage in a protocol to perform a computational task while still maintain some secure properties. Most existing approaches are required to interpret functions as a boolean circuit. With the recent state-of-art circuit garbling scheme, the performance...

  • 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 Oblivious Access to Trees

    Creator:
    Hackebeil, Gabriel A.
    Abstract:
    The outsourcing of data storage and related infrastructure to third-party services in the cloud is a trend that has gained considerable momentum in the last decade due to the savings it affords companies in both capital and operational costs. Although encryption can alleviate some of the privacy concerns associated with...

  • 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...

  • Secure socket layer protocol simulation in Java

    Creator:
    Karri, Nagendra
    Abstract:
    This project aims to study the performance of Secure Sockets Layer (SSL) Protocol implemented in JAVA for web applications. Secure Sockets Layer protocol allows client/server applications to communicate in a way that is designed to prevent eavesdropping, tampering, or message forgery. In particular, this project focuses on an implementation of...

  • 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...

  • Image Based Crypto

    Creator:
    Basa, Gungor
    Abstract:
    The ability to create reproducible cryptographically secure keys from temporal environments (e.g., images) has the potential to be a contributor to effective cryptographic mechanisms. Due to the noisy nature of these environments, achieving this goal in a user friendly fashion is a very challenging task, especially since there exists a...

  • 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...
