Secrets management

Establishing a trust environment closely aligned with your business priorities requires securing the infrastructure and software used to generate and store digital identities. Atos guarantees the highest security levels by performing key ceremonies in a highly secure environment.
The conditions for generating and storing cryptographic keys are defined during the key ceremony, and the keys are generated and stored directly in a cryptographic hardware security module (HSM).

Key custodians ensure secrecy and should be physically present during the key ceremony. The procedure is led by a master of ceremonies in a secure, fully isolated room located at IDnomic’s premises. Based on stringent, clearly defined and established procedures, the key ceremony makes it possible to:

  • Create and renew certification authorities
  • Create a certification authority revocation list
  • Migrate HSMs when equipment reaches end-of-life
  • Move from an on-premises PKI to IDnomic’s SaaS PKI

Once the ceremony has been completed, a session is held to archive the cryptographic keys in a secure space or vault.

The key ceremony and vault deposit are critical procedures to ensure that certification authorities are held securely. By generating and storing their secrets in accordance with industry best practices, clients can have real confidence and trust in the environment that IDnomic has created for their needs.

IDnomic’s facilities are compliant with the strictest security requirements. These dedicated rooms are designed specifically for storing secrets.
