ABSTRACT:
A portable security device for providing secure communications over a plurality of networks is presented. In one embodiment, the device comprises, at least one communication port for transfer of audio data, at least one communication port for transfer of digital data, a keypad, an encoding/decoding device, a conversion device operable to covert between audio and digital data and a processor, in communication with a memory, the keypad, the said encoding/decoding device, operable to execute code for selecting a configuration of a transmission and a reception port from among said communication ports dependent upon the presence of a network communication device and an input/output device in communication with said selected ports, providing data received from said selected reception port to said encryption/decryption device for encrypting; and providing said encrypted data to said selected transmission port. In one aspect of the invention, encrypted voice data can be transferred over a wireless network using cellular phones, over a wired and wireless network using land-based telephones, cellular phones or satellite phones. In another aspect, encrypted computer data may be transferred over wired or wireless networks.
