Regarding the storing of Root CA certificates on an Embedded device
Setup Explaination: 1. An embedded device which is a CLIENT on the network 2. There is a SERVER which connects to the CLIENT on SSL/TLS
Also we can access the server from any web browser. We have extracted the the following certificates from the web browser when connected to SERVER.
The certificates are
1. Root CA 2. Intermediate **CA Domain validation CA.**
It is seen that in the browser it is stores as a chain of certificates.
Now the query is do we need to store both of the certificates on our embedded devices or any one is sufficient. If only one then it should be a root CA or intermediate Domain Validation CA certificates.
Kindly need inputs asap.
Thanks in advance.
