  • 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...

  • 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...

  • 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...

  • 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...

  • Hardware realization for Advanced Encryption Standard key generation

    Creator:
    Yang, Wen-Chun
    Abstract:
    Advanced Encryption Standard (AES) is one of the secret key algorithms used in Cryptography. It is applied in a variety of applications including smart cards, internet web servers, automated teller machines (ATMs), etc. Both hardware and software implementations are taken into consideration while addressing AES algorithms. In addition to reaching...

  • 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...

  • 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...

  • Timing Attacks on Software Implementation of RSA

    Creator:
    Singh, Harshman
    Abstract:
    Timing attacks enable an attacker to extract secret information from a cryptosystem by observing timing differences with respect to different inputs given to an encryption or decryption algorithm. Werner Schindler has proposed a timing attack on smart card devices. We implemented this attack based on the same approach for RSA...

    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...

  • Random number generation on handheld devices for cryptographic applications

    Creator:
    Montville, Adam W.
    Abstract:
    Random number generation is important in many fields today. It is particularly important in the field of cryptography when generating nonce values, cryptographic keys, and other data required in many cryptographic applications. The proliferation of small, handheld devices that are typically connected to large networks via a wireless connection requires...
