Area of Science:

• Cryptography and Security
• Computer Engineering
• Embedded Systems

Background:

• Internet of Things (IoT) applications require robust security for sensitive data.
• Resource constraints (processing power, memory) in IoT devices challenge traditional cryptographic methods.
• Elliptic Curve Cryptography (ECC) is a promising solution, but its scalar multiplication is computationally intensive and energy-consuming.

Purpose of the Study:

• To explore energy-oriented improvements for Elliptic Curve Cryptography (ECC) scalar multiplication architectures.
• To develop a low-area scalar multiplication architecture for Binary Edwards Curves (BEC) suitable for IoT.
• To evaluate the hardware costs and energy efficiency of proposed optimization techniques.

Main Methods:

• Focused on energy-saving techniques applied to a low-area scalar multiplication architecture for Binary Edwards Curves (BEC).
• Designed and implemented various energy-oriented techniques in hardware.
• Developed a novel evaluation method to measure the effectiveness of these energy-saving optimizations.

Main Results:

• Reported the design and implementation costs (in hardware) for each explored energy-oriented technique.
• Demonstrated significant energy reductions in the scalar multiplication architecture.
• Achieved the most efficient area/energy trade-offs for ECC scalar multiplication in the literature, to the best of our knowledge.

Conclusions:

• The proposed energy-reducing techniques significantly enhance the efficiency of ECC scalar multiplication for IoT.
• The developed architecture offers a superior balance between area and energy consumption for resource-constrained devices.
• This work provides a valuable contribution to securing the Internet of Things (IoT) and Wireless Sensor Networks (WSN).
