The Universe Traced by Clusters
I critically review a methodology of using clusters of galaxies as cosmological probes. The understanding of the abundances and spatial correlations of dark matter halos has been significantly advanced especially for a last few years. Nevertheless such dark matter halos are not necessarily identical to clusters of galaxies in the universe. This is a quite obvious fact, but it seems that the res...
متن کاملCryptanalysis of HMAC/NMAC-Whirlpool
In this paper, we present universal forgery and key recovery attacks on the most popular hash-based MAC constructions, e.g., HMAC and NMAC, instantiated with an AES-like hash function Whirlpool. These attacks work with Whirlpool reduced to 6 out of 10 rounds in single-key setting. To the best of our knowledge, this is the first result on “original” key recovery for HMAC (previous works only suc...
متن کاملStructural Health Monitoring With Whirlpool
We propose a novel data delivery strategy, called Whirlpool, for efficient SHM using Wireless Sensor Networks. Whirlpool implements a rotating interrogation of a monitoring structure and provides collision-aware scheduling of the monitoring queries. The Whirlpool strategy can be tuned for the required Quality of Data (QoD). We apply Whirlpool to examine the unique properties of output signals o...
متن کاملThe Whirlpool Secure Hash Function
In this paper, we describe Whirlpool, which is a block-cipher-based secure hash function. Whirlpool produces a hash code of 512 bits for an input message of maximum length less than 2 bits. The underlying block cipher, based on the Advanced Encryption Standard (AES), takes a 512-bit key and operates on 512-bit blocks of plaintext. Whirlpool has been endorsed by NESSIE (New European Schemes for ...
متن کاملTraced monoidal categories BY ANDRE JOYAL
This paper introduces axioms for an abstract trace on a monoidal category. This trace can be interpreted in various contexts where it could alternatively be called contraction, feedback, Markov trace or braid closure. Each full submonoidal category of a tortile (or ribbon) monoidal category admits a canonical trace. We prove the structure theorem that every traced monoidal category arises in th...
