Rewriting Variables: The Complexity of Fast Algebraic Attacks on Stream Ciphers
Recently proposed algebraic attacks [2, 6] and fast algebraic attacks [1, 5] have provided the best analyses against some deployed LFSR-based ciphers. The process complexity is exp...

Light Space Perspective Shadow Maps
In this paper, we present a new shadow mapping technique that improves upon the quality of perspective and uniform shadow maps. Our technique uses a perspective transform specifi...

Parallel ScaLAPACK-Style Algorithms for Solving Continuous-Time Sylvester Matrix Equations
An implementation of a parallel ScaLAPACK-style solver for the general Sylvester equation, op(A)X −Xop(B) = C, where op(A) denotes A or its transpose AT , is presented. The paral...
