Carry-based Differential Power Analysis (CDPA) and its Application to Attacking HMAC-SHA-2

Transactions on Cryptographic Hardware and Embedded Systems, 2023
In this paper, we introduce Carry-based Differential Power Analysis (CDPA), a novel methodology that allows for attacking schemes that use arithmetical addition. We apply this methodology to attacking HMAC-SHA-2. We provide full mathematical analysis of

Faster bowel recovery with superior haemorrhoidal artery preservation in patients undergoing sigmoidectomy for diverticular disease: A retrospective cohort study from the diverticular disease registry trial [PDF]

Journal of Minimal Access Surgery
Introduction: The pathogenesis of diverticular disease varies significantly and so does its clinical presentation. The procedure for left-sided diverticular disease is standardised, but there is still no consensus on the level of arterial ligation.

Bicliques for Preimages: Attacks on Skein-512 and the SHA-2 family [PDF]

IACR Cryptology ePrint Archive, 2012
We present a new concept of biclique as a tool for preimage attacks, which employs many powerful techniques from differential cryptanalysis of block ciphers and hash functions. The new tool has proved to be widely applicable by inspiring many authors to publish new results of the full versions of AES, KASUMI, IDEA, and Square. In this paper, we show

Evaluating the efficacy of eggshell-derived hydroxyapatite (EHA) and synthetic hydroxyapatite (SHA) in bone regeneration of maxillofacial defects-a randomized double-blind pilot comparative clinical-radiological study [PDF]

Journal of Oral Biology and Craniofacial Research
Background: Defects of the maxillofacial skeleton lead to functional, aesthetic, social, and behavioral problems, that make the person isolate from the mainstream of society. So, bone regeneration is needed for the overall health. Since long time various

Performance Analysis of Sha-2 and Sha-3 Finalists

International Journal on Cryptography and Information Security, 2013
National Institute of Science and Technology (NIST) published the first Secure Hash Standard SHA-0 in 1993 as Federal Information Processing Standard publication (FIPS PUBS) which two years later was replaced by SHA-1 to improve the original design and added SHA-2 family by subsequent revisions of the FIPS.
