1. Integrity and Data Encryption (IDE) ECN
2. Integrity and Data Encryption (IDE) ECN – Revision A (Change Bar)
3. Integrity and Data Encryption (IDE) ECN – Revision A
Integrity & Data Encryption (IDE) provides confidentiality, integrity, and replay protection for TLPs. It flexibly supports a variety of use models, while providing broad interoperability. The cryptographic mechanisms are aligned to current industry best practices and can be extended as security requirements evolve. 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. to examine data intended to be confidential, modify TLP contents, & reorder and/or delete TLPs. 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. Compared to the Member Review copy, and consistent with the “NOTICE TO REVIEWERS” in that copy, this final revision contains significant revisions to the key management protocol in order to align it closely with the DMTF’s Secured Messages using SPDM Specification, which was not available at the time the Member Review copy was prepared. Additionally, the final copy includes significant improvements in protection against Adversary-in-the-Middle attacks, and, consistent with member feedback received in response to the query regarding key size for AES-GCM applied to IDE TLPs, supports only the 256b key size. show less
