Cows, clicks, ciphers, and satire

Stream ciphers and the eSTREAM project

Stream ciphers are an important class of symmetric cryptographic algorithms. The eSTREAM project contributed significantly to the recent increase of activity in this field. In this paper, we present a survey of the eSTREAM project. We also review recent time/memory/data and time/memory/key trade-offs relevant for the generic attacks on stream ciphers.

Subversive Satire: the Glasgow Verses

The Glasgow Verses constitutes a formal anomaly in terms of genesis, appearance and meaning. Discovered only in 1995, the verses are part of a larger text, the so-called Hunter Codex, a manuscript MaruliÊ wrote and dedicated to his friend Dmine PapaliÊ. Closer investigation revealed that this collection of poems had been entirely overlooked by traditional scholarship, and that it was neither ch...

Clicks, Concurrency, and Khoisan

I propose that the notions of segment and phoneme be enriched to allow, even in classical theories, some concurrent clustering. My main application is the Khoisan language !Xóõ, where by treating clicks as phonemes concurrent with phonemic accompaniments, the inventory size is radically reduced, so solving the problems of many unsupported contrasts. I show also how phonological processes of !Xó...

Value Flow Graph Analysis with SATIrE

This work discusses implementation of partial redundancy elimination using the value flow graph, a syntactic program representation modeling semantic equivalences. It allows the combination of simple syntactic partial redundancy elimination with a powerful semantic analysis. This yields an optimization that is computationally optimal and simpler than traditional semantic methods. A source-to-so...
