With rapid advances in information, computer and communication technologies and systems, huge amount of data has to be processed, stored and exchanged among users, which makes data integrity and information security very important issues. To protect the data and make it secure, various cryptographic primitives are being incorporated in many standards and protocols and implemented in a wide range of platforms; from powerful computers used in servers and base stations to lightweight cryptosystems used in wireless devices. The performance of cryptosystems rely heavily on efficient cryptographic computations, specially in resource constrained embedded systems, such as smart cards, RFID tags, Internet of Things, and nodes in wireless sensor networks, where the power consumption, memory, and bandwidth are very limited. Reliable and efficient design and implementation of cryptographic computations are challenging due to their complex nature. The main objectives of the research are summarized as follows:
