Physical Attacks Undermine Security of Chip-Based Trusted Execution Environments from Nvidia, AMD, and Intel

Summary
The article discusses how physical attacks are undermining the security of trusted execution environments (TEEs) from major chip manufacturers. TEEs like Nvidia's Confidential Compute, AMD's SEV-SNP, and Intel's SGX/TDX are widely used in blockchain, cloud services, AI, finance, and defense for protecting sensitive data. While these on-chip security features can withstand software-based attacks like compromised operating systems, they are vulnerable to relatively cheap physical attacks that can bypass their protections, raising concerns about the fundamental security assumptions of these widely adopted technologies.
Key quotes
· 4 pulledTrusted execution environments, or TEEs, are everywhere—in blockchain architectures, virtually every cloud service, and computing involving AI, finance, and defense contractors.
It’s hard to overstate the reliance that entire industries have on three TEEs in particular: Confidential Compute from Nvidia, SEV-SNP from AMD, and SGX and TDX from Intel.
All three come with assurances that confidential data and sensitive computing can’t be viewed or altered, even if a server has suffered a comp
On-chip TEEs withstand rooted OSes but fall instantly to cheap physical attacks.
