EmbeddedWall: 实时 CAN-FD/车载以太网报文深度检测、SecOC 认证与抗量子入口过滤

EmbeddedWall 提供片上硬件防火墙、内存保护单元 (MPU) 与总线互连访问过滤器,对后量子密码硬件加速器、安全密钥存储区及熵池种子实施物理级隔离,阻断不可信 DMA 外设与被攻陷 CPU 核心的越权探测。

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)
