On the EMD Sifting Property and Instantaneous Parameters

Multi-Property-Preserving Hash Domain Extension and the EMD Transform

We point out that the seemingly strong pseudorandom oracle preserving (PRO-Pr) property of hash function domain-extension transforms defined and implemented by Coron et. al. [12] can actually weaken our guarantees on the hash function, in particular producing a hash function that fails to be even collision-resistant (CR) even though the compression function to which the transform is applied is ...

Improved EMD Using Doubly-Iterative Sifting and High Order Spline Interpolation

Multi-Property-Preserving Hash Domain Extension: The EMD Transform

In this paper we (1) argue the benefits of replacing the current MD transform with a multi-property-preserving domain extension transform that guarantees numerous properties of the hash function assuming they hold of the compression function; (2) provide a practical, proven-secure multi-domain extension transform suitable for use with the next generation of hash functions; (3) point to some sub...

On Investigating EMD parameters to Search for Gravitational Waves

The Hilbert-Huang transform (HHT) is a novel, adaptive approach to time series analysis. It does not impose a basis set on the data or otherwise make assumptions about the data form, and so the time–frequency decomposition is not limited by spreading due to uncertainty. Because of the high resolution of the time–frequency, we investigate the possibility of the application of the HHT to the sear...
