EmbeddedWall: Real-Time CAN-FD/Ethernet Packet Inspection, SecOC & PQC Ingress Filtering

EmbeddedWall delivers on-chip hardware firewalls, memory protection units (MPU), and bus interconnect filters that physically isolate post-quantum cryptographic accelerators, secret key memories, and seed pools from untrusted DMA peripherals and compromised CPU cores.

Architectural Layers & Protocols

On-Chip Interconnect Plane (ARM CoreLink NIC-400 / AXI4 Multi-Layer Fabric): Interconnecting CPU cores, high-speed DMA masters, memory controllers, and crypto accelerators.
Hardware Transaction Filtering (Hardware Access Control Lists (ACLs)): Inspecting master IDs, privilege levels, and address ranges on every bus read/write cycle.
DMA Attack Isolation Barrier (System Memory Management Unit (SMMU / IOMMU)): Preventing compromised PCIe, USB, or Ethernet DMA controllers from probing crypto memory buffers.
Security Violation & Fault Controller (Hardware Bus Abort & State Scrubbing Logic): Terminating illicit bus cycles with zero-delay SLVERR responses and asserting security alerts.

Key Metrics: 1 Cycle (Firewall Inspection Latency) | 100% (DMA Isolation Coverage) | Hardware (Enforced Privilege Separation) | Zero-Leak (SRAM Scramble Protection)
