Data integrity through TLP encryption in PCI Express
Securing packet transfers against digital attacks
This paper discusses the flow used in the encryption of IDE TLPs in PCI Express and the underlying software stack. It explains how IDE provides security against digital attacks for TLPs sent from the transmitter to the receiver for various use models, including the transfer of data to devices connected link-to-link or devices connected through switches. It also describes the verification support that the next generation of PCIe Questa Verification IP (QVIP) provides to verify the IDE feature using a built-in sequence library, APIs, and assertions.
