Body
1. Overall Description:

O-RAN Security Work Group (WG11) is responsible for the security of the O-RAN
architecture.

WG11 is proactively preparing for the realization of cryptographically relevant
quantum computers (CRQCs) by studying post-quantum cryptography (PQC) as it
applies to O-RAN architectural elements [1]. Many IETF security protocols, e.g.
TLS, HTTPs, are used in O-RAN, and WG11 is tracking IETF’s support for PQC
algorithms into these security protocols. To help achieve a post-quantum secure
O-RAN architecture, WG11 aims to include ML-KEM [2] and ML-DSA [3] among the
quantum-safe crypto suite options within the O-RAN Technical Specifications.

WG11 is aware of the ongoing debates regarding the necessity to publish these
Internet-Drafts [4][5].

WG11 would like to express their support for publication of
draft-ietf-tls-mlkem and draft-ietf-tls-mldsa. WG11 prefers to reference RFCs.
O-RAN specifications require well maintained stable references that
internet-drafts do not provide.

2. Actions:

WG11 requests that the IETF working groups consider O-RAN's perspective during
their deliberations.

4. Meeting Schedule:

O-RAN WG11 have regular bi-weekly virtual meetings where all contributions are
considered. The next O-RAN ALLIANCE face-to-face meeting is Oct. 19-23, 2026 in
Vietnam.
