One-Trial Electromagnetic Attack on Modular Exponentiation (2008)
D. E. Lazic, Th. Beth, W. Geiselmann, P. Wichmann
Correlative side-channel attack based on ensembles of test sequences is developed. For conducted and radiated electromagnetic analysis the maximal eavesdrop distance is estimated. By a low-cost...

Wavelets and Waves in Optical Signal Preprocessing (2008)
Th. Beth, M. Schmid, D. Zerfowski
Abstract. We discuss applications of wavelet transforms in signal processing. First we consider techniques for adapted data compression, especially for medical images, to describe a given image in a...

Wavelets and Waves in Optical Signal Preprocessing (2007)
Th. Beth, A. Klappenecker, M. Schmid, D. Zerfowski
We discuss applications of wavelet transforms in signal processing. First we consider techniques for adapted data compression, especially for medical images, to describe a given image in a compact...
Probability Density Function of the Line--of--Sight Angle Error (2007)
Th Beth, M. Grassl, D. E. Lazic, H. Lukhaub
The closed form probability density function of the angle between the input and output of the time discrete AWGN channel is derived. I. Introduction Consider two N--dimensional carthesian systems N...
A Key Substitution Attack on SFLASH v3 (2007)
Willi Geiselmann, Rainer Steinw, Prof Dr, Th. Beth
A practical key substitution attack on SFLASH v3 is described: Given a valid (message, signature) pair (m; ) for some public key v 0, one can derive another public key v 1 (along with matching secret...
Wavelets and Waves in Optical Signal Preprocessing (2007)
Th. Beth, M. Schmid, D. Zerfowski
Wavelets are versatile tools in signal analysis and representation, complementing existing tools from harmonic analysis. In recent years, an upsurge of interest in wavelet methods influenced the area...

Detected jump-error correcting quantum codes, quantum error designs and quantum computation (2002)
Alber, G., Beth, Th., Charnes, Ch., Delgado, A., Grassl, M., Mussinger, M.
The recently introduced detected-jump correcting quantum codes are capable of stabilizing qubit-systems against spontaneous decay processes arising from couplings to statistically independent...
Wocjan, P., Janzing, D., Beth, Th.
We use an n-spin system with permutation symmetric zz-interaction for simulating arbitrary pair-interaction Hamiltonians. The calculation of the required time overhead is mathematically equivalent to...
