RISC-V is quietly rewriting the rules of hardware, and most security professionals aren’t prepared. This open-source chip architecture promises innovation without licensing fees, sovereign compute without vendor lock-in, and customizability at the silicon level. It’s seductive. It’s spreading fast. And it’s not nearly as secure as you’ve been led to believe.
This isn’t just a technical shift. It’s a governance breakdown, a supply chain opacity crisis, and a national security blind spot—all rolled into one.
What’s Great About RISC-V?
Before we get into the risks, let’s acknowledge why this movement has legs:
No licensing fees. Design your chips without paying ARM or Intel.
Full control. Add or strip away features at the ISA level.
Geopolitical flexibility. Nations like China are utilizing it to circumvent Western sanctions.
Custom AI and IoT potential. It’s ideal for edge computing, low-power devices, and accelerator design.
However, these same freedoms introduce significant unknowns, particularly when it comes to verifying trust in a global, opaque semiconductor supply chain.
The Hidden Risks: Open Source ≠ Open Trust
🔍 1. Tampering Below the Waterline
Most people focus on the core itself. But the real risk lives deeper—during fabrication, packaging, and firmware flashing.
Without:
Hardware Bills of Material (HBOMs)
Chip fingerprinting
Foundry attestation
…you’re trusting a black box. Even in "open" silicon.
🧪 2. Firmware Is the New Frontline
You can audit RTL logic all day, but your RISC-V chip still runs:
OpenSBI (Supervisor Binary Interface)
U-Boot or other bootloaders
OS transitions and privilege handlers
If those are insecure, all bets are off. And most are shipped with default configs that wouldn't pass even a basic red team sniff test.
🌐 3. Export Controls Are Dead in the Water
This one’s strategic: RISC-V’s open nature nullifies national control over who builds what. There's no U.S. Commerce “entity list” for open-source hardware. That’s great for global collaboration—and a nightmare for dual-use containment.
If you’re worried about adversarial access to advanced compute, RISC-V just made the problem exponentially harder.
🤖 4. AI + RISC-V = Ghost in the Machine
As RISC-V becomes the backbone for AI accelerators—especially at the edge—you’re embedding silicon of unknown origin in:
Surveillance devices
Battlefield sensors
Critical infrastructure
Your AI model might be fine. Your chip might not be.
What Smart Security Leaders Should Be Doing Now
🔐 1. Treat Hardware Like Open Software
Use approved, auditable core repositories
Demand secure boot + firmware signing as a baseline
Avoid chips without runtime telemetry or secure enclaves
🔍 2. Ask Hard Questions in Procurement
Where was this chip fabricated?
Can you prove the provenance back to RTL?
Is your firmware build reproducible and signed?
If your vendor can't answer those, they shouldn't be in your system.
🤝 3. Push for a “UL for Open Silicon”
We need a neutral, certifiable standard for RISC-V cores, SoCs, and toolchains. Until that happens, you're on your own.
Let’s stop pretending that “open” absolves risk. It simply redistributes it onto your security team.
Final Thought
RISC-V is inevitable. But inevitability isn’t the same as trustworthiness. We can’t rely on legacy thinking—or legacy procurement models—to protect us in a post-x86, post-ARM world.
Security leaders must engage now. Build assurance into your silicon stack. Advocate for transparency, not just openness. And never confuse public access with public safety.
The next significant breach won’t start with software.It’ll start with a core you didn’t vet.Etched into silicon.Baked into your systems.Invisible—until it’s not.
