Lightweight ECC with Fragile Zero-Watermarking for Internet of Things Security

Elliptic Curve Cryptography (ECC) is one of the approaches that provide security and privacy in distributed resource constrained IoT environment with high computational efficiency and less energy consumption. However, the use of Elliptic Curve Digital Signature (ECDSA) for authenticity of IoT users require complex operations in signature generation and verification with high memory consumption. Therefore, we propose a lightweight ECCWatermark scheme that can overcome the ECC-based schemes limitation by using a fragile zero watermarking technique instead of digital signature for authentication. We evaluate the approach with other existing ECC schemes including ECC standard, EC-Schnorr and ECC-Montgomery.
