IACR Cryptol. ePrint Arch., 2012 This paper presents high-speed assembly implementations of the 256-bit-output versions of all five SHA-3 finalists and of SHA-256 for the ARM11 family of processors. We report new speed records for all of the six implemented functions. For example our implementation of the round-3 version of JH-256 is 35% faster than the fastest implementation of the ...

Classification of the SHA-3 Candidates
IACR Cryptol. ePrint Arch., 2008 In this note we give an overview on the current state of the SHA-3 candidates. First, we classify all publicly known candidates and, second, we outline and summarize the performance data as given in the candidates documentation for $64$-bit and $32$-bit implementations. We define performance classes and classify the hash algorithms.

New hash function based on C-MD structure and chaotic neural network
网络与信息安全学报, 2023 In recent years, widely used hash algorithms such as MD5 and SHA-1 have been found to have varying degrees of security risks.The iterative structure of the SHA-2 algorithm is similar to that of SHA-1, making it vulnerable to attacks as well.Meanwhile ...

Dosimetry, Toxicity and Stability Associated With a Hyaluronic Acid-Based Prostate-Rectal Spacing Device During Prostate Radiation Therapy: A Retrospective Comparative Analysis. [PDF]
J Med Radiat SciRectal spacers composed of stabilised hyaluronic acid facilitated a favourable toxicity profile compared to no spacing during prostate radiation therapy. Acute GI toxicity (grade ≥ 1) was lower in the spacer cohort (23.5% vs. 48.0%; odds ratio = 0.33, p = 0.05) with grade ≥ 2 toxicity substantially lower (2.9% vs. 20.0%).
