Hardware Evaluation of SHA-3 Candidates
… and exploits on the cryptographic hash function, SHA-1, the most widely used hash function of the secure hashing algorithm family. Although these attacks do not work on SHA-2, the next in the series of the secure hashing algorithm family, the National Institute of Standards and Technology still …

Fair Comparison of ASIC Performance for SHA-3 Finalists
… different constraints for secure algorithms, SHA-3 finalists, which includes Blake, Groestl, Keccak, JH, and Skein, have been chosen as the ones to be implemented for experiments in this thesis. This thesis has first explored the effects of different synthesis constraints on ASIC performance, …

Secure and Efficient Implementations of Cryptographic Primitives
… a hardware evaluation methodology to the NIST SHA-3 standardization process. Our research efforts cover both of the SHA-3 fourteen Second Round candidates and five Third Round finalists. We design the first SHA-3 benchmark chip and discuss the technology impact to the SHA-3 hardware evaluation …

Security proofs for the MD6 hash function mode of operation
… commonly-used hash functions, such as MD4, MD5, SHA-0, and SHA1 [13, 38]. These culminated with the celebrated work of Wang, Yin, and Yu from 2005, which demonstrated relatively efficient methods for finding collisions in the SHA-1 hash function [37]. Although there are several cryptographic hash …

Advances in the Side-Channel Analysis of Symmetric Cryptography
… SCA of the new secure hashing function mbox{SHA-3}. Although the main application of mbox{SHA-3} is hashing, there are other keyed applications including Message Authentication Codes (MACs), where protection against SCA is required. We study the SCA properties of all the operations involved …

Differential Power Analysis In-Practice for Hardware Implementations of the Keccak Sponge Function
… to develop the Secure Hash Algorithm-3 Standard (SHA-3). Prior work has developed reference implementations of the algorithm and described the structures necessary to harden the algorithm against power analysis attacks which can weaken the cryptographic properties of the hash algorithm. This work …

Single-trace template attacks on permutation-based cryptography
… recovery on target intermediate bytes in the SHA3-512 hash function implemented on an 8-bit device, which I combined with a three-layer enumeration technique for error correction to recover all the input values of this hash function from a single trace recording. To demonstrate an alternative …

Vector Instruction Set Extensions for Efficient and Reliable Computation of Keccak
… Standard (AES), for the Secure Hashing Standard (SHA-1, SHA2) and for carry-less multiplication. These crypto-instructions are optimized for a single algorithm and provide significant performance improvements over software written using general-purpose instruction set. However, today's secure …

Cryptographic coprocessors for embedded systems
… of recent hash function designs from the SHA-3 competition are discussed and a fair comparison methodology for hash functions presented. Many cryptographic protocols involve the generation of random data, for keys or nonces. This requires a True Random Number Generator (TRNG) to be present …
