Technologies for secure I/O redirection include a provider device, a consumer device, an authentication server, and a messaging server. The provider device and the consumer device establish an authenticated I/O redirect pairing. The authentication server authenticates the consumer device, and, if authenticated, generates a pairing identifier and provides the pairing identifier to the provider device and the consumer device. The redirect pairing is associated with the shared pairing identifier, a shared encryption key, and one or more shared message topics. The provider device and the consumer device subscribe to the messaging server as publisher and/or listener using the shared message topics. The provider device and the consumer device encrypt I/O data using the shared encryption key and encapsulate the encrypted I/O data into messages using the shared message topics. The provider device and the consumer device exchange the messages using the messaging server. Other embodiments are described and claimed.
