Visualising Sha[2] in Abelian surfaces [PDF]
Mathematics of Computation, 2004 Given an elliptic curve E1 over a number field and an element s in its 2-Selmer group, we give two different ways to construct infinitely many Abelian surfaces A such that the homogeneous space representing s occurs as a fibre of A over another elliptic curve E2.

A High-Efficiency FPGA-Based Multimode SHA-2 Accelerator [PDF]
IEEE Access, 2022 The secure hash algorithm 2 (SHA-2) family, including the SHA-224/256/384/512 hash functions, is widely adopted in many modern domains, ranging from Internet of Things devices to cryptocurrency. SHA-2 functions are often implemented on hardware to optimize performance and power.

Implementation of reconfigurable SHA-2 hardware core [PDF]
APCCAS 2008 - 2008 IEEE Asia Pacific Conference on Circuits and Systems, 2008 Secure Hashing Algorithm (SHA) is increasingly becoming popular for the online security applications, specifically, for mobile and embedded system platforms. This necessitates a high performance hardware implementation of the four most utilized SHA algorithms (SHA-224, SHA-256, SHA-384, SHA-512).

Cryptanalysis of Dynamic SHA(2) [PDF]
, 2009 In this paper, we analyze the hash functions Dynamic SHA and Dynamic SHA2, which have been selected as first round candidates in the NIST hash function competition. These hash functions rely heavily on data-dependent rotations, similar to certain block ciphers, e.g., RC5.

Stressor- and Corticotropin releasing Factor-induced Reinstatement and Active Stress-related Behavioral Responses are Augmented Following Long-access Cocaine Self-administration by Rats [PDF]
, 2008 Rationale Stressful events during periods of drug abstinence likely contribute to relapse in cocaine-dependent individuals. Excessive cocaine use may increase susceptibility to stressor-induced relapse through alterations in brain corticotropin-releasing

Preimages for Step-Reduced SHA-2 [PDF]
, 2009 In this paper, we present preimage attacks on up to 43-step SHA-256 (around 67% of the total 64 steps) and 46-step SHA-512 (around 57.5% of the total 80 steps), which significantly increases the number of attacked steps compared to the best previously published preimage attack working for 24 steps.

Improving SHA-2 Hardware Implementations [PDF]
, 2006 This paper proposes a set of new techniques to improve the implementation of the SHA-2 hashing algorithm. These techniques consist mostly in operation rescheduling and hardware reutilization, allowing a significant reduction of the critical path while the required area also decreases.
