AEGIS: Thermodynamic State Space Models for Zero-Day Network Evasion Detection

arXiv·medium signalXBlueskyLinkedInCopy link

AEGIS introduces a thermodynamic variational state space model for detecting zero-day network evasion attacks that bypass existing TLS 1.3 encrypted traffic classifiers. Recent pre-padding attacks reduced ET-BERT accuracy to 25.68%, and VLESS Reality bypasses certificate-based detection entirely. AEGIS uses entropy-guided immune system principles to detect adversarial byte-level morphing in encrypted traffic. Addresses a critical gap as TLS 1.3 encryption limits traditional deep packet inspection.
