A note on distinguishing attacks

A new distinguishing attack scenario for stream ciphers, allowing a resynchronization collision attack, is presented. The attack can succeed if the part of the state that depends on both the key and the IV is smaller than twice the key size. It is shown that the attack is applicable to block ciphers in OFB mode. For OFB mode, the attack is more powerful than the previously known generic distinguis

On the Efficient Frequency Estimation of a Single Tone

The frequency estimation of a single tone corrupted by additive white Gaussian noise has received significant attention over the last decades due to its wide applicability in signal processing. In this paper, we propose a computationally fast and statistically improved hybrid single tone estimator which outperforms other recently proposed approaches, lowering the signal-to-noise ratio at which the

Den (o)hållbara förpackningen

I Den [o] hållbara förpackningen analyseras svenska konsumentförpackningar från 1930-talet fram till idag. Boken består av tre delar där läsaren först får lära känna mjölkförpackningarna, som är livsmedelsbranschens kanske vanligaste men samtidigt mest krävande förpackning. Därefter behandlas läkemedelsförpackningarna, en kategori som alltid har kännetecknats av ett högt säkerhetstänkande. Slutlig

Conceptual Metaphors of Science : Prolegomena to a Cognitive History of Science

The cognitive abilities explained by cognitive science and cognitive semantics can inform us concerning the use of metaphors in science. The thesis is that abstract ideas rest on experiences of the concrete world. In this paper I will explain the use of conceptual metaphors in science, with examples from the mechanistic worldview of the 17th and 18th century. If we proceed from the way people thin
