Integrating Elliptic Curve Cryptography for Secure Key Exchange in Mobile SMS Communication

Psalms Chinemere Kalu, and Moses Okechukwu Onyesolu

Abstract

The rapid growth of mobile communication has made short message service an essential means of information exchange. However, its inherent vulnerabilities make it susceptible to interception, identity spoofing, and unauthorized access. This paper presents a secure SMS communication framework that integrated Elliptic Curve Cryptography for efficient key exchange, combined with the Advanced Encryption Standard for message confidentiality and SHA-256 for integrity verification. The secure SMS communication framework ensures end-to-end encryption and cross-platform operability while maintaining computational efficiency suitable for mobile devices. Implementation results demonstrated significant improvements in security and performance compared to conventional RSA-based systems. This hybrid cryptographic design offers a viable model for secure, scalable, and lightweight mobile communication.
