[...]... practical solution for embedded systems and high-speed applications It was therefore planned to conduct a study of high-speed cryptographic solutions onreconfigurable hardware platforms Both efficient and cost effective solutions of cryptographicalgorithms are desired onreconfigurable logic platform The term "efficient" normally refers to "high speed" solutions In this Book, we do not only look for... most emblematic algorithms, namely, the Data Encryption Standard (DES) and the Advance Encryption Standard (AES) In the case of asymmetric cryptosystems we analyze fast implementations of Elliptic Curve operations defined over binary extension fields Several considerations were made to achieve high speed and economical implementations of those algorithmsonreconfigurable logic platforms One of them was... from the cryptographicalgorithms of layer 1, it is indispensable to have an eflftcient implementation of arithmetic operations such as, addition, subtraction, multiplication, exponentiation, etc In the rest of this Chapter we give a short introduction to the algorithms and security services listed in layers 2-4 Hence, the basic concepts of cryptography, fundamental operations in cryptographic algorithms. ..
