New physical attacks are quickly diluting secure enclave defenses from Nvidia, AMD, and Intel
Trusted 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 complete compromise of the operating kernel. A trio of novel physical attacks raises new questions about the true security offered by these TEES and the exaggerated promises and [...]
