We would like to explain why AES instructions should be considered: Based on our observation that Intel CPU performance figures of several SHA-3 candidates are due to the use of instructions in SSE, we think that new version of SSE which employs AES instructions should be considered as the same way as the current version of it. We expect that Intel CPUs with AES instructions will be widely used...

Hardware implementation of the main building block (compression function) for five different SHA-3 candidates is presented. The five candidates, namely Blue Midnight Wish, Luffa, Skein, Shabal, and Blake have been considered since they present faster software implementation results compared to the rest of the SHA-3 proposals. The compression functions realized in hardware create the message dig...

Skein is a submission to the NIST SHA-3 hash function competition which has been optimized towards implementation in modern 64-bit processor architectures. This paper investigates the performance characteristics of a high-speed hardware implementation of Skein with a 0.18 μm standard-cell library and on different modern FPGAs. The results allow a first comparison of the hardware performance fig...

Blue Midnight Wish hash function is one of 14 candidate functions that are continuing in the Second Round of the SHA-3 competition. In its design it has several S-boxes (bijective components) that transform 32-bit or 64-bit values. Although they look similar to the S-boxes in SHA-2, they are also different. It is well known fact that the design principles of SHA-2 family of hash functions are s...

There exists a broad range of RFID protocols in literature that propose hash functions as cryptographic primitives. Since Keccak has been selected as the winner of the NIST SHA-3 competition in 2012, there is the question of how far we can push the limits of Keccak to fulfill the stringent requirements of passive low-cost RFID. In this paper, we address this question by presenting a hardware im...

BACKGROUND AND PURPOSE Given the challenges posed by surgical clipping, endovascular techniques have been increasingly used to treat SHA aneurysms. The purpose of this study was to assess the safety and efficacy of endovascular techniques in the treatment of SHA aneurysms. MATERIALS AND METHODS Medical charts and initial and follow-up angiograms were reviewed retrospectively for all patients ...

We present the hash function BLAKE2, an improved version of the SHA-3 finalist BLAKE optimized for speed in software. Target applications include cloud storage, intrusion detection, or version control systems. BLAKE2 comes in two main flavors: BLAKE2b is optimized for 64-bit platforms, and BLAKE2s for smaller architectures. On 64bit platforms, BLAKE2 is often faster than MD5, yet provides secur...
