Methods and systems for providing and controlling cryptographic secure communications terminal providing a remote desktop accessible in secured and unsecured environments

Abstract

Methods and systems for operating a remote desktop client from a computing system hosting a secure boot device. In some embodiments, a method comprises initiating execution of an operating system from the computing system hosting the secure boot device, the computing system communicatively connected within a secure enterprise network, the computing system being untrusted within the secure enterprise network and based on verification of received authentication credentials, booting an operating system from the secure boot device and establishing a secure communication tunnel with a service appliance. Further, the method comprises receiving, from the service appliance a destination address of a secure gateway device connected to the enterprise network and community of interest keys and filters based on the authenticated credentials; and establishing a cleartext communication channel with the secure gateway device, thereby allowing communication between the computing system and one or more trusted endpoints within the secure enterprise network.
