Balanced permutations Even-Mansour ciphers

The r-rounds Even–Mansour block cipher is a generalization of the well known Even–Mansour block cipher to r iterations. Attacks on this construction were described by Nikolić et al. and Dinur et al. for r = 2, 3. These attacks are only marginally better than brute force but are based on an interesting observation (due to Nikolić et al.): for a “typical” permutation P, the distribution of P(x)⊕ ...

writing system that we know to be a derived one. This early branching point is thus the equivalent of speciation in biological evolution. The separate writing systems of these neighbouring regions must have been mutually incomprehensible. Over a short time span — three centuries at most, but probably much less — the proto-Elamite script spread across Iran, offering a prime example of cultural d...

Using the participation in peer reviewed publications of all doctoral students in Quebec over the 2000-2007 period this paper provides the first large scale analysis of their research effort. It shows that PhD students contribute to about a third of the publication output of the province, with doctoral students in the natural and medical sciences being present in a higher proportion of papers p...
