Methods and systems for switching between multiple languages of a remote desktop client operating on a secure boot device are disclosed. A method includes initiating an operating system from the secure boot device and receiving credentials including a user identification and a password. The method also includes booting, from the secure boot device, the operating system in a first language and receiving a selection of a second language different from the first language within a user interface of the operating system. The method further includes performing a desktop reset to execute the operating system in the second language.

Methods and systems for providing and controlling cryptographic secure communications terminal operable in a plurality of languages

Virtual machines in a network may be isolated by encrypting transmissions between the virtual machines with keys possessed only by an intended recipient. Within a network, the virtual machines may be logically organized into a number of community-of-interest (COI) groups. Each COI may use an encryption key to secure communications within the COI, such that only other virtual machines in the COI may decrypt the message. Remote devices may gain access to virtual machines in a network through a virtual device relay. The virtual device relay receives data from the remote device, such as a tablet or cellular phone, and forwards the data to one of the virtual machines, when the virtual device relay shares a COI with the destination virtual machine.

Methods and systems for providing and controlling cryptographic secure communications terminal operable to provide a plurality of desktop environments

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.

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

Methods and systems of communicating with secure endpoints included within a secured network from a mobile device external to the secured network is disclosed. The method includes initiating a VPN-based secure connection to a VPN appliance, and initializing a stealth-based service on the mobile device. The method further includes transmitting user credential information from the mobile device to a VDR broker via the VPN appliance, and receiving status information from the VDR broker identifying a VDR associated with the mobile device and providing a connected status. The method also includes communicating with one or more secure endpoints within the secured network via a VPN connection to the VDR via the VPN appliance and through the VDR to the one or more secure endpoints within a community of interest based on the user credential information transmitted to the VDR broker.

A method and apparatus for reusing a thread for different programmed operations are provided in various embodiments. In one embodiment, different application operations are defined as subclasses of a thread operation class, and a thread is implemented with a thread class. In one embodiment, the application operations can be queued to the thread for scheduled execution using the thread. In another embodiment, a first application operation can start a thread and be executed therewith, while a second application operation can attach to the thread for execution.

Method and apparatus for resuse of a thread for different programmed operations

A system and method for managing a pool of threads for executing thread operations. A thread pool is instantiated which includes a plurality of threads, and a work queue having program controllable states is instantiated. Thread operations are queued to the work queue when the work queue is in a running or suspended state, and when the work queue is in a stopped state requests to queue thread operations are denied. The work queue supports controlled allocation of thread resources to a variety of thread operations.
