TEE Engineer License case studies
TEE Engineer License · Put your knowledge to work in context.
The TEE Engineer License is a professional credential for engineers who design, build, and assess Trusted Execution Environments (TEEs). It targets software developers, firmware and platform security engineers, and security assessors who need to demonstrate working knowledge of isolation architectures, secure boot and attestation flows, trusted application development, vulnerability analysis, and confidential computing deployment. The TEE Engineer License case studies are 5 cases and about 3,595 words.
1Threat Modeling a TEE License Vault on a Rooted Set-Top Box
Your company ships 12 million set-top boxes. Each box runs a TrustZone-based TEE: the secure world holds content-decryption keys and a license counter, while the normal world runs a Linux stack that any owner can root.

An industrial operator has 8,000 battery-powered gateways in remote substations. Each gateway boots with a ROM verifier that checks an RSA-3072 bootloader against a root-key hash burned into OTP, then measures the OS and a container.

A payment trusted application runs in a GlobalPlatform TEE on a handheld POS terminal. The TA has a 64 KB heap, a 32 KB stack, and a single thread.

You are the independent evaluator for a smart-home hub that uses a vendor TEE to protect Wi-Fi credentials and cloud tokens. The vendor claims the TEE is resistant to “software and physical attacks.” In a four-week lab assessment you find: (1) a cache-timing side channel in the TEE’s AES-GCM implementation that leaks four bits of the authentication key per 10,000 encryptions to a co-resident normal-world process, and (2) a voltage-glitch fault injected during secure boot that skips the signature check on roughly one in 5,000 boots, after which the device boots an unsigned image but still reports “secure boot enabled” over the local API.

A bank wants to move its fraud-scoring service into confidential VMs on a public cloud using AMD SEV-SNP. Three subsidiaries will submit sensitive transaction data; the bank’s on-premises HSM will release a data-encryption key only after verifying an attestation report.
