John have subscribed to a cloud-based service to synchronize data between your mobile device and your PC. Before allowing the data to be synchronized, this service uses a process where the cloud service and the client on the mobile device verify each other's security certificates.

What is this process called?

Mutual authentication

Explanation: Mutual authentication could be referred to a vetting process where the two entities in communication authenticate each other, it could also be referred to as a two-way authentication.

In the scenario above, the cloud service or server authenticates itself with the client and the client authentication itself with the cloud service server by verifying or vetting the certificates of both communicating entities before a secure encrypted connection would be established or created.
