In this paper we propose a fully-parallel, bit-sliced unified architecture designed to perform modular multipication/exponentiation and GF(2^M) multiplication as the core operations of RSA and EC cryptography. The architecture uses radix-2 Montgomery technique for modular arithmetic, and a radix-4 MSD-first approach for GF(2^M) multiplication. To the best(More)
In this paper we present a hardware implementation of the RSA algorithm for public-key cryptography. Basically, the RSA algorithm entails a modular exponentiation operation on large integers, which is considerably time-consuming to implement. To this end, we adopted a novelalgorithm combining the Montgomery's technique and the carry-save representation of(More)
Early prediction of hardware complexity is essential in driving hardware/software partitioning and the automatic generation of HDL descriptions from high-level code. In fact, early prediction helps estimate the “hardware cost” of a given high-level code segment before the actual synthesis, dramatically reducing the time required for an(More)
In this paper we present an hardware implementation of the RSA algorithm for public-key cryptography. The RSA algorithm consists in the computation of modular exponentials on large integers, that can be reduced to repeated modular multiplications. We present a serial implementation of RSA, which is based upon an optimized version of the RSA algorithm(More)
Semantic Interoperability is one of the most important open challenges in the Knowledge Management field. In this work, we propose a framework for making easier information exchanging operations among heterogeneous information sources, over the Cloud. Exploiting the Semantic Web technologies, the framework has the objective of allowing semantic(More)
One of the main open issues in the development of applications for sensor network management is the definition of interoperability mechanisms among the several monitoring systems and heterogeneous data. Interesting researches related to integration techniques have taken place, they are primary based on the adoption of sharing data mechanisms. In the last(More)
