Cryptanalysis of the CFVZ cryptosystem
The paper analyzes CFVZ, a new public key cryptosystem whose security is based on a matrix version of the discrete logarithm problem over an elliptic curve. It is shown that the co...

Non-contiguous linear placement for reconfigurable fabrics
: We present efficient solutions for the non-contiguous linear placement of data-paths for reconfigurable fabrics. A strip-based architecture is assumed for the reconfigurable fabr...

Rational Univariate Reduction via toric resultants
We describe algorithms for solving a given system of multivariate polynomial equations via the Rational Univariate Reduction (RUR). We compute the RUR from the toric resultant of ...

Polynomial-Time Complexity for Instances of the Endomorphism Problem in Free Groups
Abstract. We say the endomorphism problem is solvable for an element W in a free group F if it can be decided effectively whether, given U in F , there is an endomorphism φ of F ...

Extremal Problems of Information Combining
Abstract--In this paper, we study moments of soft bits of binary-input symmetric-output channels and solve some extremal problems of the moments. We use these results to solve the ...
