Central System: Guard Filter Core - Ingress PQC Inspector

Cryptographic Nodes

  • TLS 1.3 Term
  • Downgrade Block
  • WAF Rules
  • mTLS Mesh
  • eBPF Fast Path

Architectural Layers & Protocols

  • eBPF Packet Steering & Ingress Filter (Kernel-Level XDP (eXpress Data Path)): Inspecting TLS ClientHello messages and steering PQC traffic without user-space context switches
  • Downgrade Protection Engine (Cryptographic Negotiation State Machine): Rejecting handshakes that strip post-quantum key shares when interacting with critical services
  • Application Layer WAF & Policy Controller (Dynamic Context-Aware Ingress Filtering): Inspecting API payloads, sanitizing JWTs, and verifying post-quantum client identities
  • High-Speed Hardware Acceleration Hub (PCIe Cryptographic Accelerator Cards): Offloading ML-KEM polynomial calculations to preserve host CPU cores for application logic

Key Metrics: 0 Fallbacks (Unapproved Classical Downgrades) | <0.2 ms (Proxy Ingress Overhead) | 40 Gbps (Line-Rate Inspection) | Hardware Enforced (Policy Strictness)

防止企业边缘的协议降级攻击

During the multi-year transition from classical to post-quantum cryptography, attackers will exploit legacy fallback mechanisms to force connections down to vulnerable RSA or ECDH ciphers. MLKEMGuard strictly enforces quantum-resilient transport policies.
