Preimages for Step-Reduced SHA-2 [PDF]
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.

Applying Grover's Algorithm to Hash Functions: A Software Perspective
Quantum software frameworks provide software engineers with the tools to study quantum algorithms as applied to practical problems. We implement classical hash functions MD5, SHA-1, SHA-2, and SHA-3 as quantum oracles to study the computational resource ...

Implementation of reconfigurable SHA-2 hardware core [PDF]
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).

Enhanced immunogenicity of stabilized trimeric soluble influenza hemagglutinin. [PDF]
The recent swine-origin H1N1 pandemic illustrates the need to develop improved procedures for rapid production of influenza vaccines. One alternative to the current egg-based manufacture of influenza vaccine is to produce a hemagglutinin (HA) subunit ...

Search framework for neutral bits and boomerangs in SHA‐1 collision attacks
Neutral bits and boomerangs are key techniques for accelerating collision search in SHA‐1 attacks. The current acceleration techniques for SHA‐1 near‐collision attacks are reviewed and a generic search framework for neutral bits and boomerangs is ...

Time–space complexity of quantum search algorithms in symmetric cryptanalysis: applying to AES and SHA-2 [PDF]
Performance of cryptanalytic quantum search algorithms is mainly inferred from query complexity which hides overhead induced by an implementation. To shed light on quantitative complexity analysis removing hidden factors, we provide a framework for ...

Cryptanalysis of Dynamic SHA(2) [PDF]
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.
