Core engineering and protocols for DMA Attack Mitigation.
Modern SoCs grant high-speed peripherals (Ethernet, Wi-Fi, USB, PCIe) Direct Memory Access (DMA) to system RAM to achieve high throughput without burdening the main CPU. However, if an adversary compromises a peripheral's firmware, they can instruct the DMA controller to read arbitrary memory addresses, stealing post-quantum private keys directly from application memory buffers.
EmbeddedWall sits directly between the peripheral bus masters and the system memory interconnect. Every read and write transaction is validated in single-cycle hardware against pre-configured access control tables. If a network controller attempts to access addresses belonging to the cryptographic engine or its secure SRAM, the transaction is physically blocked.
