Abstract
Rapidly growing speed of quantum computing introduces unprecedented danger to modern cryptographic solutions, so security beyond typical encryption is imperative. Here, we present a hybrid cryptosystem consisting of chaotic map-based keystream generation, DNA-inspired quaternary encoding, and quantum-enhanced key generation. This architecture is constructed to address post-quantum security needs, while preserving computational efficiency for encryption of high-value information. Experimentation results confirm that hybrid key generation has a near-maximum entropy of 7.97 bits per byte, and passes benchmarks that are applied in the modern dataset. Multilayer encryption cascade, with deterministic chaos and DNA encoding, achieves a 96.8% avalanche effect, which means it possesses strong diffusion characteristics. Comparing AES-256-GCM and ChaCha20-Poly1305, we see competitive security–throughput trade-offs. Moreover, the machine learning–based analytics layer on encrypted metadata shows 93.8% accuracy on CICIDS2017 dataset, without impacting the core cryptographic security, maintaining formal security integrity and reproducibility.
