Trusted Computing: Confidentiality, Integrity, and Side-Channel Attacks

This lecture covers the fundamentals of trusted computing, focusing on the need for confidentiality and integrity in hardware and software. It explains trusted hardware properties, such as attestation, sealing, and isolation, and discusses technologies like Trusted Platform Module (TPM) and Trusted Execution Environments (TEE). The lecture also delves into real-world examples, such as private contact discovery in Signal, and explores side-channel attacks like Meltdown and Spectre, emphasizing the importance of mitigations and the challenges of ensuring security in trusted computing environments.
