AWS shows how to enforce approved post-quantum signing algorithms with SCPs and IAM
In short: AWS published a follow-up security guide explaining how organizations can enforce which ML-DSA (post-quantum signature) parameter sets are allowed across their AWS environment. It covers using Service Control Policies (SCPs) at the organization or OU level and IAM permission boundaries to block creation and use of non-approved ML-DSA variants (e.g., blocking ML-DSA-44 while allowing ML-DSA-65/87). The guide also covers AWS Private CA and certificate controls, and discusses the trade-off between deny-lists (default-allow for new variants) and allow-lists (default-deny, requiring policy updates for new approved algorithms).

What changed?
- 1AWS KMS supports three ML-DSA (FIPS 204) parameter sets: ML-DSA-44, ML-DSA-65, ML-DSA-87
- 2Example SCPs shown to deny creation and usage (Sign/Verify/GetPublicKey) of specific key specs like ML_DSA_44
- 3kms:KeySpec is the reliable control lever; kms:SigningAlgorithm cannot distinguish ML-DSA variants since all use ML_DSA_SHAKE_256
- 4SCPs do not apply to the organization's management account
- 5Controls only cover AWS service APIs (KMS, Private CA, ACM), not cryptography run on EC2/containers/Lambda or protocol-level use like OpenSSH hybrid keys
Why it matters
Organizations beginning to adopt post-quantum cryptography need practical ways to standardize on specific algorithm parameter sets and prevent drift; this gives security/compliance teams concrete IAM/SCP patterns to do that at scale on AWS.
What it means for AI agents and contact centers
If your infrastructure runs on AWS and uses AWS KMS, Private CA, or ACM for code signing or certificate management, this provides a template for restricting which cryptographic algorithms can be used organization-wide; otherwise it has limited direct relevance to voice AI or contact-center systems.
