PCI Express Security and TEE Integration, Part 1 - Establishing Trust
Protecting processor memory alone is no longer sufficient. The entire I/O path must become part of the trusted computing architecture. To address this challenge, PCI-SIG® has developed a suite of complementary security technologies, including Data Object Exchange (DOE), Component Measurement and Authentication (CMA), Integrity and Data Encryption (IDE), and the TEE Device Interface Security Protocol (TDISP).
