Abstract. Canetti and Rabin recently proposed a universally composable ideal functionality FSIG for digital signatures. We show that this functionality cannot be securely realized ...
In this paper we study the long standing problem of information extraction from multiple linear approximations. We develop a formal statistical framework for block cipher attacks b...
In this article we present some weaknesses in the RC4 cipher and their cryptographic applications. Especially we improve the attack described in [2] in such a way, that it will wo...
Linear optimization queries retrieve the top-K tuples in a sliding window of a data stream that maximize/minimize the linearly weighted sums of certain attribute values. To effici...
In this paper, we propose a preprocessing method to improve Side Channel Attacks (SCAs) on Dual-rail with Precharge Logic (DPL) countermeasure family. The strength of our method i...
