Abstract: The present invention provides an encrypting device including an encryption unit and a communications unit. Paired encrypting devices allow for communication of trusted data between trusted devices over an untrusted network. Data received by the encryption unit is encrypted and provided with a connectionless header for delivery to the communications unit. Data received by the communications units is provided with a complex header for delivery to the paired encrypting device. The encrypting devices may be implemented in hardware or may be virtualized on a server or a plurality of severs. Arrangement of the encrypting devices in a hub-and-spoke topology allows for communication amongst a plurality of trusted devices. The encrypting devices can be used to covert commercially available equipment suitable for high assurance environments.
