LH-SHIELD and ASKA Integration Demo

Description of LH-SHIELD in ASKA Integration Diagram:

This diagram illustrates how LH-SHIELD’s Physical Layer (L1) is deeply integrated into the larger ASKA system. It highlights that, within ASKA, LH-SHIELD L1 becomes specifically the interface to ASKA’s broader hardware-level security framework.

• LH-SHIELD L1 as ASKA Physical Verification Layer: The LH-SHIELD Physical Layer (L1) - ASKA Integrated subgraph represents how LH-SHIELD’s L1 components are tailored for ASKA integration. The key component becomes Physical Verification Matrix (PVM), which acts as the explicit interface point to ASKA’s I/E Aggregator.
• Hardware Attestation within ASKA Trust Framework: Within L1 (now within ASKA context), the TPM Bridge, Platform Configuration Registry (PCR), and Runtime Trust Service (RTS) components from LH-SHIELD’s L1 remain. They still provide hardware attestation, platform state measurement, and runtime trust evaluation. However, now, their output (Runtime State and Trust Signals) flows directly into ASKA’s broader security framework, specifically into Trust Vector Matrix (TVM) and Channel Authentication Matrix (CAM).
• ASKA I/E Aggregator Interaction (PVM): Physical Verification Matrix (PVM) is shown explicitly interacting with ASKA’s I/E Aggregator via a bi-directional arrow AIE <--> PVM. This symbolizes the direct hardware-level verification integration between LH-SHIELD L1 and ASKA’s external system boundary – physical-layer security directly informing ASKA’s ingress/egress enforcement.
• Hardware-Verified Channels and Integration with LH-SHIELD Core: Channel Authentication Matrix (CAM) and Channel Configuration Manager (CCM) still perform channel verification functions, but crucially, the CCM now outputs “Verified Channels (HW Verified)” to the rest of LH-SHIELD Core Layers – specifically to L2 (L2[LH-SHIELD Identity & Authentication (L2)]). This connection CCM -->|Verified Channels (L2 Integration)| L2 illustrates that LH-SHIELD’s L2 and higher layers benefit from the hardware-backed channel verification provided by the integrated L1 (within ASKA framework).
• LH-SHIELD Core Layers (L2-L6) Remain Structurally LH-SHIELD: The LH-SHIELD Core Layers (L2-L6) subgraph (dashed box, greyed out style to visually de-emphasize as focus is L1 integration into ASKA in this diagram) visually represents that the structure of L2, L3, L4, L5, and L6 from LH-SHIELD largely remains within the ASKA integration. These layers are still LH-SHIELD protocol implementations for identity, secure channels, capabilities, sandbox, and audit – however, they are enhanced and underpinned by the ASKA-integrated Physical Layer L1. Dashed lines connecting these core LH-SHIELD layers signify they are conceptually present as LH-SHIELD layers, but the diagram’s primary focus and detailed representation is on L1 integration into ASKA’s framework.

Key Takeaways from ASKA Integration Diagram:

• LH-SHIELD L1 as ASKA’s Physical Security Extension: In this integrated view, LH-SHIELD’s Physical Layer becomes a specialized, ASKA-integrated physical verification and attestation layer within the broader ASKA security architecture.
• Hardware-Backed Trust Amplifies LH-SHIELD Security: ASKA’s hardware-level verification and trust signals from the integrated LH-SHIELD L1 significantly strengthen the security of all higher layers of LH-SHIELD (L2-L6) when deployed within an ASKA-protected system.
• Hybrid Approach - Best of Both Worlds: The ASKA integration represents a hybrid architecture that combines ASKA’s broader external system security and hardware-level verification focus with the principled layered protocol architecture of LH-SHIELD, achieving a synergistic security posture – hardware-rooted trust underpinning a robust layered software security framework.
