Abstract
The rapid proliferation of Internet of Things (IoT) devices and blockchain technology requires robust and efficient cryptographic solutions to ensure secure communication and data integrity. This paper presents an optimized Edward-Elgamal signature algorithm that uses Edward curved signature storage mechanism to improve performance in IoT and blockchain environments to overcome the limitations of schemes, especially Elliptic Curve Digital Signature Algorithm (ECDSA) and Hyper-ECDSA. The proposed method achieved faster signature generation times, with a 33% improvement over ECDSA and a 25% improvement over Hyper-ECDSA, making it more suitable for faster applications. The validation times of the optimized systems were relatively low, with a 32% improvement over ECDSA and a 24% improvement over Hyper-ECDSA. The efficiency of the proposed system was significantly higher, showing a 51% improvement over ECDSA and a 35% improvement over Hyper-ECDSA. The latency was reduced by 33% compared to ECDSA and 26% compared to Hyper-ECDSA, indicating the effectiveness of the optimized system in terms of time-related performance. This paper contributes to the advancement of cryptographic techniques and provides suitable solutions for secure IoT and blockchain applications. The proposed system achieves a highest improvement rate in key performance parameters over existing methods, resulting in a robust solution for modern cryptography requirements.
