Abstract

Secure communication has become a critical requirement with the rapid advancement of digital systems and the increasing exposure of sensitive information to cyber threats. Conventional cryptographic mechanisms primarily rely on mathematical key generation techniques, which are vulnerable to key theft, replay attacks, and emerging quantum computing capabilities. To address these challenges, this paper proposes a novel cognitive–quantum secure communication framework that integrates electroencephalogram (EEG)–based thought recognition with deep learning and post-quantum cryptography. The proposed system utilizes EEG signals captured during controlled cognitive stimuli to generate unique, human-dependent cryptographic keys. A hybrid CNN–LSTM model is employed to learn and generalize thought-specific brainwave patterns across multiple users, enabling reliable cognitive classification. The generated cognitive features are transformed into dynamic cryptographic keys through quantization and genetic mutation, ensuring high sensitivity to both mental state and temporal variations. To achieve quantum resistance, the framework integrates AES-256 symmetric encryption with post-quantum cryptographic algorithms such as HQC for key encapsulation and CRYSTALS-Dilithium for authentication. Additionally, Quantum Key Distribution (QKD) is incorporated to enable secure key synchronization with time-offset validation, effectively mitigating replay and interception attacks. Experimental evaluation demonstrates high entropy, strong key sensitivity, and reliable cognitive verification accuracy, ensuring that decryption is possible only when the correct thought pattern is reproduced within the valid time window. The results confirm that combining human cognition with quantum-safe cryptography significantly enhances security, robustness, and future resilience, making the proposed system suitable for next-generation secure communication applications.
