Abstract: Ensuring secure wireless communications without degrading reliability is a key challenge in modern communication systems. In this talk, Elliptic Curve Modulation (ECM) is introduced, which a novel modulation framework that leverages the well-distributed properties of elliptic curve points to provide strong symbol obfuscation at the physical layer while preserving the symbol error probability (SEP) performance of conventional unencrypted modulation schemes. ECM maps symbols based on predefined keys while maintaining minimum Euclidean distance constraints, enabling effective physical-layer encryption without compromising error performance. Building on this concept, we present ECM with Dynamic Rotation (ECM-DR), a practical scheme that combines a reduced subset of precomputed elliptic curve points with key-based constellation rotation to achieve near-maximal obfuscation with manageable complexity. The talk will highlight the security properties of ECM, its resilience against brute-force attacks, and its potential as a robust solution for secure wireless communications.
