The Rectangle Attack - Rectangling the Serpent
Serpent is one of the 5 AES finalists. The best attack published so far analyzes up to 9 rounds. In this paper we present attacks on 7-round, 8-round, and 10-round variants of Serpent. We attack a 7round variant with all key lengths, and 8and 10-round variants with 256-bit keys. The 10-round attack on the 256-bit keys variants is the best published attack on the cipher. The attack enhances the ...

متن کاملLattice points in a rectangle
Basically, what we can try to do is to take the Fourier transform of 1R (the indicator function for the set R), and then use Fourier inversion to show that for each shift t+L of the lattice L, this shift intersects the set R. Actually, it will not quite be enough to take the Fourier transform of just 1R, but instead we will need to work with a smoothed version of 1R in order to make the Fourier...
متن کاملTiling a Rectangle with Polyominoes
A polycube in dimension d is a finite union of unit d-cubes whose vertices are on knots of the lattice Zd . We show that, for each family of polycubes E, there exists a finite set F of bricks (parallelepiped rectangles) such that the bricks which can be tiled by E are exactly the bricks which can be tiled by F . Consequently, if we know the set F , then we have an algorithm to decide in polynom...
متن کاملMoving a Rectangle around a Corner: Geometrically
In [8], Moretti presented the problem of moving a couch around a corner as a challenging one for calculus students. It is interesting to solve the same problem by simple Euclidean geometry, in the same spirit as the author’s solution of L’Hospital’s Pulley Problem [2], namely, to stress mathematical concerns whose importance has been made increasingly evident by developments in computer science...
