Analysis of SHA-512/224 and SHA-512/256

In 2012, NIST standardized SHA-512/224 and SHA-512/256, two truncated variants of SHA-512, in FIPS 180-4. These two hash functions are faster than SHA-224 and SHA-256 on 64-bit platforms, while maintaining the same hash size and claimed security level. So far, no third-party analysis of SHA-512/224 or SHA-512/256 has been published. In this work, we examine the collision resistance of step-redu...

Npgrj_nn_1413 512..518

Neurobiological studies demonstrate the amygdala’s role in emotional memory, and psychological studies suggest a particular pattern: enhanced memory for the gist but not the details of complex stimuli. We hypothesized that these two findings are related. Whereas normal (n 5 52) and brain-damaged (n 5 22) controls showed the expected enhancement of gist memory when the encoding context was emoti...

This paper presents the algorithmic aspects of organization of a lowcomplexity fully parallel processor unit for constant matrix-vector products computing. To reduce the hardware complexity (number of twooperand multipliers), we exploit the Winograd’s inner product calculation approach. We show that by using this approach, the computational process of calculating the constant matrix-vector prod...

Collision attack on NaSHA-512

The hash function NaSHA [1] is a new algorithm proposed for SHA-3. The compression function adopts quasigroup transformations, which raise obstacles to analysis. However, the high probability difference to cause inner collision can be found in the quasigroup transformations. We propose a collision attack to NaSHA-512 with the time complexity 2 and negligible memory, which is lower than the comp...
