How location verification would work
The United States is advancing tamper-proof location verification technology for advanced AI chips, aiming to create a "Find My" system for semiconductors that would make it far harder for restricted processors to be smuggled to China.
The effort combines proposed legislation, the Chip Security Act of 2026, with emerging hardware-level tracking methods being developed by chip designers and security researchers.
Physical Location Verification (PLV) systems would embed tamper-resistant location tracking directly into export-controlled AI chips and the computers that house them.
According to IEEE Spectrum, the approach would require covered AI chips and listed computers to carry location verification hardware that can cryptographically prove their geographic position.
The tracking would not rely on an always-on internet connection — chips would periodically attest to their location using a combination of GPS, network triangulation, and cryptographic time-stamping.
Sovereignty certificates are a key concept: tamper-resistant hardware on the chip generates a cryptographic certificate attesting to the chip's location at a given time, signed by a trusted authority.
If a chip designated for a data center in Taiwan surfaces at a server farm in China, the certificate chain breaks, triggering an alert and potentially disabling the chip.
The smuggling problem
The US first imposed export controls on advanced AI chips in 2022, restricting sales of Nvidia's A100, H100, and later H200 processors to China. Enforcement has been inconsistent.
Investigators have found restricted chips in Chinese data centers, routed through intermediaries in Singapore, Malaysia, and Thailand.
In one case reported this year, US authorities approved sales of H200 chips to a Chinese company whose listed office address turned out to be an empty room.
A Congressional Research Service report estimated that China has acquired thousands of export-controlled AI chips through third-party intermediaries since the controls were tightened.
The Biden administration's 2023 expansion of restrictions covered chips with specific performance characteristics, but without hardware-level location attestation, enforcement depends on paper trails and spot checks.
The Chip Security Act
The Chip Security Act, introduced in Congress earlier this year, would require the Commerce Department to mandate location verification on export-controlled AI chips and listed computers within 180 days of enactment.
The bill covers both hardware-level tracking and data center location reporting requirements. Importers of restricted chips would need to certify the chips' final destination and provide ongoing location verification.
Senate sponsors of the bill argue that software-only tracking is insufficient. A hardened supply chain requires chips that can cryptographically prove they remain in permitted jurisdictions throughout their operational life.
Technical challenges
Building tamper-resistant location verification into advanced processors is technically demanding. Researchers at MIT and the University of Michigan have demonstrated proof-of-concept PLV systems, but scaling them to million-chip production runs presents cost and reliability questions.
The verification hardware must be resistant to physical tampering, side-channel attacks, and GPS spoofing.
Chip manufacturers including Nvidia and AMD have engaged with policymakers on the technical requirements, according to the IEEE Spectrum report.
Industry participants have raised concerns about yield impacts from adding tamper-resistant modules to advanced chip designs, especially when chip geometries are already pushed to their physical limits.
Parallel efforts in Europe and Japan
The US is not alone in pursuing chip location verification. The European Union's Chips Act includes provisions for supply chain security, and Japan has begun pilot programs for tracking advanced semiconductor equipment.
A coordinated approach among allied nations would make it harder for restricted chips to find secondary markets.
Implications for AI development
If implemented at scale, hardware-level location verification could reshape the global AI chip market. Chinese AI labs that have relied on smuggled Nvidia hardware would face tighter supply constraints.
Cloud providers operating in permitted jurisdictions would need to demonstrate ongoing compliance. And the technology could eventually extend beyond AI chips to other export-controlled hardware, from lithography equipment to quantum computing components.
The IEEE Spectrum report positions the effort as a race: smugglers are getting more sophisticated, and the US needs chip-level enforcement to keep pace.
Whether the technology can be deployed before the next generation of export controls is tested by evasion remains an open question.
