Abstract: Disclosed is a method for execution by a computing device. The method involves establishing a communication channel for communicating with a client device using link-layer encryption, and attempting to authenticate the client device using authentication-layer encryption on top of the link-layer encryption. The method also involves receiving a command from the client device over the communication channel, and if the client device has been authenticated, executing the command. Notably, the link-layer encryption offers some degree of security because network traffic over the communication channel is encrypted, but does not offer adequate protection from all cyber attacks. However, the authentication-layer encryption adds an additional layer of security on top of the link-layer encryption, which can help to avoid or mitigate cyber attacks.
