Systems and methods for securely communicating with a server device are provided. Both the server device and a client device may be provided pre-shared keys, which may be based on a stream of random digits generated by a quantum random number generator. The client device may promote a new client-side key from among the pre-shared keys for use in secure communication with the server device in response to an event, such as a time-based event (e.g., passage of 30 seconds). The server device may be substantially synchronized with the client device such that a server-side key matches a client-side key being used to communicate securely with the server device.
