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...

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...

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...

A comparative study of AES implementations on ARM processors

Creator:: Shamsuddin, Rayees
Abstract:: AES (Advanced Encryption Standard), also known as Rijndael, is a symmetric key block cipher adopted as an encryption standard by the US government and used extensively in cryptographic applications worldwide. ARM is the most popular processor core used in embedded applications. This thesis surveys the available public implementations of AES...

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...

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...

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...

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...

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...
