EmbeddedWall: 실시간 CAN-FD/이더넷 심층 패킷 검사, SecOC 인증 및 PQC 인그레스 필터링

EmbeddedWall는 온칩 하드웨어 방화벽, 메모리 보호 장치(MPU) 및 버스 상호 연결 필터를 제공하여 양자 내성 암호 가속기, 비밀 키 메모리 및 시드 풀을 신뢰할 수 없는 DMA 주변 장치 및 침해된 CPU 코어로부터 물리적으로 격리합니다.

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)
