IGC-Santé - Health Cryptographic Key Infrastructure

A platform to help streamline and secure health data transmission

What is the Health CKI?

The IGC-Santé is a cryptographic key infrastructure (CKI) run by the ANS. Its mission is to secure the sharing of health data. Since 2021, it is the unique authorised entity in France to issue software certificates.

Technical officers in health structures and practices are able to generate, renew and revoke the certificates. To gain access to the IGC-Santé, they need a card issued by the ANS or a ProSantéConnect ID. These certificates are used by health professionals to identify themselves, sign and encrypt information.

As a software publisher or health industrial, there are 3 main benefits when you integrate the IGC-Santé:

  • It guarantees your identity or the identity of an addressee, for instance via digital signature;
  • You benefit from the legitimacy carried through by the ANS;
  • It’s a safe way to exchange data in a secure way, by encrypting and decrypting information.

  • Place an order
    To place an order, select your Profile and your Structure, then choose “Produits de développement. Commander des produits de développement : carte et/ou certificat logiciel de test" (Test products for products, cards and/or test software)

Step 2: Technical phase

Use the card you validated after step 1 in order to connect with the Trusted Platform IGC-Santé. You will be able to order, withdraw, monitor and revoke test certificates through the IHM or Webservice interface.
In order to do so, make sur you have inserted your test card in the card reader.

The IGC-Santé is dedicated to the health sector and follows strict procedures in terms of data collection, professional identification, and works with certified authorities (RPPS register, etc.).

The certificates issued by the IGC guarantee the security of software or electronic cards, such as the CPS card.

The IGC also manages the publication of these certificates and can revoke them – this is signalled to the apps using certificates in revocation listings.

There are two main reasons for the creation of IGC-Santé :

  • Guaranteeing the security of private keys and certificates issued by the ANS: the access to these private keys must be limited in order to prevent duplicates or their installation more than one device;
  • Maintaining a continuity in services: many health apps used to work on certificates issued by former CKI that ceased their activity in January 2021. These apps must be compatible with certificates issued by the IGC-Santé.

In addition, these certificates meet the security standards (risk analysis, safety policies), or “Certifying Policies” that comply with the PGSS-IS guidelines.
