Hi bschmidt,
I think the question is more if you would like to store such important data on an edge device.
Our ctrlX CORE would be the right device to collect all the values.
It security certified, so no one, which has not the rights, can access it. Additionally we have a Telegraf app which can send the data signed and encrypted to a database.
From my point the influxdb can be the right database for such a time series. It should maybe hosted in some safe environment like a small or bigger datacenter, which can also be on premise at your customer. Influxdb itself has aswell some user management which defines who is allowed to do what.
Would be interesting what your solution is at the end.
