This research presents Quantum-Entangled Lattice-Augmented Cryptographic System (QELACS) a next-generation hybrid cryptographic framework that fuses quantum entanglement with algebraic lattice-based encryption to deliver quantum-safe, scalable, and high-performance data security. Unlike traditional hybrid models that merely layer quantum and classical methods, QELACS deeply integrates quantum mechanics into the cryptographic core, enabling entanglement-assisted operations across the encryption lifecycle. The framework introduces three foundational algorithms: Entanglement-Augmented Secret Key Generation (EASKG) for ultra-secure and rapid key production, Quantum-Lattice Encryption and Decrypt... More >
