EmbeddedWall: Inspeção de Pacotes CAN-FD/Ethernet em Tempo Real, SecOC e Filtragem PQC

O EmbeddedWall fornece firewalls de hardware on-chip, unidades de proteção de memória (MPU) e filtros de interconexão de barramento que isolam fisicamente aceleradores criptográficos pós-quânticos, memórias de chaves secretas e pools de sementes contra periféricos DMA não confiáveis e núcleos de CPU comprometidos.

EmbeddedWall Interconnect Architecture & Bus Firewall Topology

AXI4 bus filter, DMA memory protection unit, and hardware privilege domain barrier

Central System: Bus Firewall Controller - AXI/AHB Interconnect Filter

Cryptographic Nodes

  • AXI4 Firewall Filter
  • DMA Isolation Unit
  • Privilege Domain Tracker
  • Cryptographic RAM Enclave
  • Bus Violation Alarmer

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)

Firewall de Barramento PQC Reforçado por Hardware, Unidade de Proteção de Memória (MPU) de Interconexão AHB/AXI e Isolamento de Ataques DMA
