Master the foundation of all hardware security: establishing and maintaining trust from power-on to runtime
Understand how hardware establishes trust from immutable silicon roots through the entire boot process to runtime operations.
Learn UEFI Secure Boot, Intel Boot Guard, and how each stage verifies the next component in the boot chain.
Master TPM-based measurement and remote attestation protocols that prove system integrity to external verifiers.
Why we need immutable hardware anchors in an era of sophisticated attacks
Everything can be modified by attackers!
Trust anchored in unchangeable hardware!
Malware that infects the boot process before OS loads, nearly impossible to detect or remove
Hardware RoT: Blocks unsigned boot componentsPhysical access to modify firmware or install hardware implants
Hardware RoT: Detects unauthorized modificationsNation-state actors compromising supply chain or firmware
Hardware RoT: Validates authentic components onlyUEFI rootkits, SMM exploitation, BMC compromise
Hardware RoT: Establishes clean execution environmentCompare different approaches to establishing immutable trust anchors

Prove platform integrity to remote verifiers without physical access
System being verified
System requesting proof
Verifier → Attester: "Prove your integrity"
Attester: Collect current PCR values
TPM: Sign measurements + nonce with AIK
Attester → Verifier: Signed attestation quote
Verifier: Validate signature and compare measurements
Verify datacenter servers before deploying sensitive workloads
ECU attestation before safety-critical operations
Manufacturing equipment verification for safety and quality
Payment terminal attestation before transaction processing
