Visualizing Elements of Sha[3] in Genus 2 Jacobians [PDF]

, 2010
Mazur proved that any element xi of order three in the Shafarevich-Tate group of an elliptic curve E over a number field k can be made visible in an abelian surface A in the sense that xi lies in the kernel of the natural homomorphism between the cohomology groups H^1(k,E) -> H^1(k,A).

Hardware Performance Evaluation of SHA-3 Candidate Algorithms

Journal of Information Security, 2012
Secure Hashing Algorithms (SHA) showed a significant importance in today’s information security applications. The National Institute of Standards and Technology (NIST), held a competition of three rounds to replace SHA1 and SHA2 with the new SHA-3, to ensure long term robustness of hash functions.

Asymptotic Analysis of Plausible Tree Hash Modes for SHA-3 [PDF]

IACR Transactions on Symmetric Cryptology, 2017
Discussions about the choice of a tree hash mode of operation for a standardization have recently been undertaken. It appears that a single tree mode cannot address adequately all possible uses and specifications of a system. In this paper, we review the

SAT-based analysis of SHA-3 competition finalists

Numerical Methods and Programming (Vychislitel'nye Metody i Programmirovanie)
Рассматриваются финалисты конкурса SHA-3, организованного для принятия нового стандарта криптографической хеш-функции. Все пять финалистов до сих пор являются стойкими к поиску прообраза, т.е. для них невозможно за реальное время найти вход по известному выходу.

Concurrent Error Detection for Reliable SHA-3 Design [PDF]

Proceedings of the 26th edition on Great Lakes Symposium on VLSI, 2016
Cryptographic systems are vulnerable to random errors and injected faults. Soft errors can inadvertently happen in critical cryptographic modules and attackers can inject faults into systems to retrieve the embedded secret. Different schemes have been developed to improve the security and reliability of cryptographic systems. As the new SHA-3 standard,
