Repeater Insertion Techniques for 3D Interconnects

Giovanni De Micheli, Vasileios Pavlidis

A new approach for inserting repeaters in 3-D interconnects is proposed. The allocation of repeaters along an interplane interconnect is iteratively determined. The proposed approach is compared with two other techniques based on conventional methods used ...

Reducing Memory Requirements for Combinatorial Attacks on NTRU via Multiple Birthdays

In this paper we view the possibilities to lance a multiple (iterative) birthday attack on NTRU. Recently Wagner's algorithm for the generalized birthday problem [9] allowed to speed-up several combinatorial attacks. However, in the case of NTRU we can not ...

Parallelization of the LEMan Code with MPI and OpenMP

Wilfred Anthony Cooper, Nicolas Mellet

The low-frequency wave propagation code LEMan has been parallelized. Due to large memory requirement but fast computation with the cold model, the parallelization is limited to a low number of processors. The specific block-tridiagonal structure of the mat ...

The Complexity of Distinguishing Distributions

Serge Vaudenay, Thomas Baignères

Cryptography often meets the problem of distinguishing distributions. In this paper we review techniques from hypothesis testing to express the advantage of the best distinguisher limited to a given number of samples. We link it with the Chernoff informati ...

Diffusion LMS algorithms with information exchange

Ali H. Sayed

We consider the problem of distributed estimation, where a set of nodes are required to collectively estimate some parameter of interest. We motivate and propose new versions of the diffusion LMS algorithm, including a version that outperforms previous sol ...

A co-design platform for Algorithm/Architecture design exploration

Marco Mattavelli, Christophe Lucarz, Julien Dubois

The efﬁcient implementation of multimedia algorithms, for the ever increasing complexity of the speciﬁcations and the emergence of the new generation of processing platforms characterized by multicore and multicomponent parallel architectures, requires app ...

Improved Related-Key Attacks on DESX and DESX+

In this paper, we present improved related-key attacks on the original DESX, and DESX+, a variant of the DESX with its pre- and post-whitening XOR operations replaced with addition modulo

A profiling framework for high level design space exploration for memory and system architectures

In 1971, the first microprocessor produced in mass production had 2300 transistor and was able to compute 60'000 operations per second at 740 kHz. Nowadays, even a common gaming console uses a central unit including 243 millions of transistors running at 4 ...

Reduced complexity attacks on the alternating step generator

Willi Meier, Shahram Khazaei, Simon Fischer

In this paper, we present some reduced complexity attacks on the Alternating Step Generator (ASG). The attacks are based on a quite general framework and mostly benefit from the low sampling resistance of the ASG, and of an abnormal behavior related to the ...

Bayesian Factorial Linear Gaussian State-Space Models for Biosignal Decomposition

Silvia Chiappa

We discuss a method to extract independent dynamical systems underlying a single or multiple channels of observation. In particular, we search for one dimensional subsignals to aid the interpretability of the decomposition. The method uses an approximate B ...
