How does encryption work to protect information on remote workers' computers?

It is difficult to set up, so an unskilled attacker won't be able to figure it out.

Without the proper key, an attacker won't be able to unscramble the encrypted information.

Using encryption requires advanced training in mathematics, which is beyond the capabilities of most attackers.

Information can be encrypted but it can never be decrypted leaving an attacker unable to read the information
