![]() ![]() TLP traffic can be secured as it transits Switches, extending the security model to address threats from reprogramming Switch routing mechanisms or using “malicious” Switches. to examine data intended to be confidential, modify TLP contents, & reorder and/or delete TLPs. The security model considers threats from physical attacks on Links, including cases where an adversary uses lab equipment, purpose-built interposers, malicious Extension Devices, etc. The cryptographic mechanisms are aligned to current industry best practices and can be extended as security requirements evolve. ![]() It flexibly supports a variety of use models, while providing broad interoperability. view more Integrity & Data Encryption (IDE) provides confidentiality, integrity, and replay protection for TLPs. Integrity & Data Encryption (IDE) provides confi. PCI Express Base Specification Revision 6.0.1, Version 1.0 ![]() In cases where the Platform detects that an incompatible Adapter is installed, the Platform may choose to not power the Adapter or isolate the affected sideband signals to avoid damage or interface instability. The VIO_CFG signal is intended to provide the Platform an indication of the IO voltage capabilities of the M.2 Adapter installed. This provides IO voltage flexibility to enable IO voltage levels other than 3.3V in the applicable M.2 form factors. ![]() VIO 1.8V, a 1.8V IO Voltage source (one pin) The VIO 1.8 V signal is intended as an IO supply and reference voltage for host interface sideband signals PERST#, CLKREQ#, and PEWAKE# and additional signals such as SUSCLK, W_DISABLE1#, W_DISABLE2#.VIO_CFG, a 1.8V IO support indication (one pin).This support adds two previously defined pins to these LGAs: view more This ECN adds 1.8V IO support to Type 1216, Type 2226, and Type 3026 LGAs. This ECN adds 1.8V IO support to Type 1216, Type 222. ![]()
