- Introducing PCIes Integrity and Data Encryption Feature (IDE)
The Integrity and Data Encryption (IDE) was published in PCIe (Peripheral Component Interconnect Express) version 6 0, and it was created as a tool to protect the communication between the different devices of the PCIe topology root complex (RC), switch (SW), and endpoint (EP)
- Is PCIe TX RX are reversible? - NVIDIA Developer Forums
Lane reversal means lanes-0,1,2,3 going to lanes-3,2,1,0 and polarity reversal means swapping Tx+ to Tx- and or Rx+ to Rx- If the above is what is present in the design, it should work
- Integrity and Data Encryption (IDE) ECN Deep Dive
Overview: PCIe® Technology Encryption (IDE) Goals: Provide confidentiality, integrity, and replay protection for PCIe Transaction Layer Packets (TLPs) Support wide variety of use models Broad interoperability Aligned to industry best practices extensible
- PCIes IDE Encryption and Integrity enhance data security
PCIe's IDE Encryption and Integrity boost data security by ensuring encrypted storage and protection against unauthorized access and data tampering
- PCIe Link Training Overview - Texas Instruments
Peripheral Component Interconnect Express (PCIe) is a motherboard expansion bus standard introduced in 2003 to enable high-speed serial communication between the Central Processing Unit (CPU) and its peripheral components
- Compute Express LinkTM (CXLTM) Link-level Integrity and Data Encryption . . .
Adversaries and threats Simple or skilled hardware adversaries Physical attacks on the link such as use of interposers to snoop, modify, inject or replay data or headers, device swap (trusted device with untrusted one) TCB IDE blocks in root-port and end-points CXL switch Agent that establishes the IDE session
- IDE Security IP for PCIe 5. 0 | Synopsys
The Synopsys Integrity and Data Encryption (IDE) Security IP Module for PCIe 5 0 provides confidentiality, integrity, and replay protection for Transaction Layer Packets (TLP) over PCI Express interfaces as defined in the PCI-SIG IDE specification
- Why IDE Security Technology for PCIe and CXL?
IDE is a key feature that would help make PCIe Links secure IDE adds additional latency and complexity to the existing PCIe IP stack and will be enhanced for the upcoming PCIe 6 0 and CXL 3 0 with the FLIT revisions
