Further technical details
What is required?
Smart Metering PKI certificates
You will require three different certificates, which are issued by a Sub Certificate Authority (List of registered Sub-CAs).
- TLS
- Signature
- Encryption
In order to request them, you need to (apart from a lot of paperwork) send a technical signed certificate request and prove to the Sub-CA, that you are able to handle the processes defined in the Smart Metering PKI. Those include (among others):
- Compliance with encryption standards
- Ability to check for revoked certificates
- Renew your certificate
- Revoke your certificate
In general, you have to renew your certificate every two years and be able to handle your partners renewals as well.
