In this paper proposes an integrated security model based on Elliptic Curve Cryptography (ECC), combining the Elliptic Curve Digital Signature Algorithm (ECDSA) and the Elliptic Curve Integrated Encryption Scheme (ECIES) into a unified framework. This model addresses the limitations of traditional cryptographic schemes, such as RSA, by providing equivalent security with much shorter keys and lower computational costs. Using a common elliptic curve structure, the proposed system reduces implementation complexity and enhances efficiency, making it suitable for resource-constrained environments, such as IoT devices and medical sensors. Experimental results demonstrate a 40% improvement in processing time and a 78% reduction in power consumption compared to traditional hybrid systems. The model also enhances resistance to known attacks by applying data hiding techniques during encryption. This work demonstrates a promising direction toward secure and efficient communications in next-generation networks and applications.
