The key is to keep the implementation as simple as possible (attestation via Intel Trust Authority or mTLS) and not include poison pills like kill switches and geofencing that would make this unworkable and too onerous for end-users and chip designers alike END

Dmitri Alperovitch @dmitri.silverado.org · 16/07/2025
Through this lens, the Chip Security Act or similar solutions would help accomplish the goal of identifying export control violators with minimal overhead to AI chip companies and exporters
180
Dmitri Alperovitch @dmitri.silverado.org · 16/07/2025
The goal here would not be to identify and stop every AI chip export violation but to collect additional data that might help identify export control violators
120
Dmitri Alperovitch @dmitri.silverado.org · 16/07/2025
In another scenario, if you have a customer that has purchased tens of thousands of AI chips which are not reporting in every month (accounting for typical chip failure rates, etc), it is also grounds for a BIS investigation of an importer
120
Dmitri Alperovitch @dmitri.silverado.org · 16/07/2025
A typical hop between eg Shanghai and Singapore will add 40-300ms of consistent latency which can be easily detected. This would then be a clue for BIS to investigate further
120
Dmitri Alperovitch @dmitri.silverado.org · 16/07/2025
To mitigate against this, the exporter's webserver can measure round trip time (RTT) for packets inside the mTLS connection and then compare it to pings to the IP from which the connection is originating
120
Dmitri Alperovitch @dmitri.silverado.org · 16/07/2025
Of course, this is not full-proof. Chinese companies can purchase AI chips through shell companies elsewhere, reship the chips to China and then proxy their mTLS connections through VPNs and proxies in countries where the shell companies are based
120
Dmitri Alperovitch @dmitri.silverado.org · 16/07/2025
Another way to accomplish this might to be use existing Intel Trust Authority for GPU remote attestation architecture that Intel and Nvidia have partnered on but that creates a requirement to use Intel CPUs, which may not be ideal in every case docs.trustauthority.intel.com/main/article...
docs.trustauthority.intel.com
GPU Remote Attestation With Intel® Trust Authority | Intel® Tiber™ Trust Authority
Learn about the Intel® Trust Authority Python Client, CLI for Intel TDX and NVIDIA GPU, and Intel Trust Authority REST API that support GPU attestation.

Dmitri Alperovitch @dmitri.silverado.org · 16/07/2025
GPU drivers can already do mTLS handshake operations like ECDSA signing, so this doesn’t even require any new code from the chip designers
120
Dmitri Alperovitch @dmitri.silverado.org · 16/07/2025
The connection can be trivially initiated via a simple script from other parts of the environment where the AI chip is deployed, but just talk to the GPU driver for handshake initiation/client key exchange with the EXPORT_CERT. This minimizes the technical reqs for AI chips
120
Dmitri Alperovitch @dmitri.silverado.org · 16/07/2025
The mTLS connection would not originate from the chip itself. In fact, it doesn’t even have to originate from the server that the chip is in
120
Dmitri Alperovitch @dmitri.silverado.org · 16/07/2025
So if a chip is being sold to a data center in Singapore but the connection originates from an IP address in China (or anywhere else), well, that means you might have a potential transshipment on your hands that warrants BIS investigation
120
Dmitri Alperovitch @dmitri.silverado.org · 16/07/2025
The US exporter would then have the country from where the secure mTLS conn is originating from and match it against the customer KYC and export info data that they had been collected during the export process to determine whether country of shipment matches country of use
120
Dmitri Alperovitch @dmitri.silverado.org · 16/07/2025
US exporters would run mTLS webservers with public key versions of the EXPORT_CERTs loaded on them (they would get them from the chip designers) to record the IP addresses and their geolocation from where the connections are originating
121
Dmitri Alperovitch @dmitri.silverado.org · 16/07/2025
Foreign end-users (wouldn’t apply to US customers or perhaps to trusted foreign govs) would then be obligated by BIS to use this cert for mTLS (mutual-auth) Client Key Exchange connection generation to the US exporter of the chip on a periodic basis (ex. once a week/month)
120
Dmitri Alperovitch @dmitri.silverado.org · 16/07/2025
New AI chips going forward can incorporate a new certificate with a private key (EXPORT_CERT) in their Secure Enclave (they already have other certs for secure boot/attestation). So this is a very simple task
120
Dmitri Alperovitch @dmitri.silverado.org · 16/07/2025
Here is one technical solution for chip location verification that can be easily implemented by AI chip designers, which is not onerous and won’t require GPS receivers or comms functionality inside the chip or significantly restrict its use in air gap environments👇

Dmitri Alperovitch @dmitri.silverado.org · 16/07/2025
CSA bill should tell BIS to rely on NIST to come up with the appropriate technical solution that is as technically simple as possible for both chip designers, exporters, and end-users
120
Dmitri Alperovitch @dmitri.silverado.org · 16/07/2025
CSA won’t solve every problem and it’s not full-proof (evasions can still occur although will be harder to pull off) but it does provide additional resources to identify malign actors that have gone undetected in opaque supply networks
120
Dmitri Alperovitch @dmitri.silverado.org · 16/07/2025
The most important thing about the Chip Security Act and why it’s different from other proposals is that it is an investigative tool for enforcement, not an enforcement mechanism on its own
120
Dmitri Alperovitch @dmitri.silverado.org · 16/07/2025
The idea behind CSA is not to prevent chips from working in banned locations like China but to simply expose more data to exporters of chips (and ultimately US BIS) on their end-users to enhance investigations of transshipping violators
120
Dmitri Alperovitch @dmitri.silverado.org · 16/07/2025
It is also important that Congress avoid imposing a specific technical approach on the industry (it’s not good at that), nor require geofencing or kill switches built into chips that would turn this into an unworkable solution
131
Dmitri Alperovitch @dmitri.silverado.org · 16/07/2025
The idea of chip geolocation is not new but various proposals have been plagued over the years with technical challenges, over-engineering complexity, and the perfect approach being the enemy of the “good enough”
120
Dmitri Alperovitch @dmitri.silverado.org · 16/07/2025
By allowing China to procure advanced AI chips, such as those from Nvidia and AMD, we are literally arming our enemy for a potential conflict with us and this has to be addressed with tightening and stricter enforcement of chip export controls
120
Dmitri Alperovitch @dmitri.silverado.org · 16/07/2025
Some have estimated that as many as 30% of American GPUs are being diverted to China today but real numbers are impossible to validate because of the current ease of diversion
120
Dmitri Alperovitch @dmitri.silverado.org · 16/07/2025
AI chip diversion to China is a huge problem as it is not only helping CN companies in competition with US firms in the most important industry of the future - AI, but also helps them develop advanced weapons systems that we and our allies would confront in a potential conflict
120
Dmitri Alperovitch @dmitri.silverado.org · 16/07/2025
Chip Security Act (CSA) is a new bipartisan bill in Congress that requires advanced AI chips to have location verification to combat illicit diversion of exports of these chips to banned countries like China. A 🧵 on how this could work to enhance US export control enforcement
