Software-based cryptography can be used for security applications where data traffic is not too large and low encryption rate is tolerable. But hardware methods are more suitable where high speed and real-time encryption are needed. Until now, there has been no book explaining how the main cryptographic algorithms can be implemented on reconfigurable hardware devices. This monograph shows how high-speed cryptographic algorithms implementations can be achieved on reconfigurable hardware devices such as Field Programmable Gate Arrays (FPGAs) without posing prohibitively high requirements for hardware resources. Due to their reconfigurable properties, keys can be changed rapidly, and basic primitives in most cryptographic algorithms can efficiently be implemented in FPGAs. This book covers computational methods, computer arithmetic algorithms, and design improvement techniques needed to implement efficient cryptographic algorithms in FPGA reconfigurable hardware platforms. The author emphasizes practical aspects of reconfigurable hardware design, explaining the basic mathematics involved, and reviewing state-of-the-art implementation techniques.
