Abstract
A method for selectively encrypting electronically communicated information including the steps of: in a first mode, allowing audio and facsimile signals to pass between communications devices in a substantially unaltered manner; in a second mode: establishing a secure session between a first security device and a second security devices; intercepting and digitizing audio signals to produce audio data; encrypting the audio data; and, modulating the encrypted audio data for transmission over the secure session; and, in a third mode: automatically intercepting a signal indicative of an attempt to transmit or receive a facsimile; establishing a facsimile session dependent upon at least one characteristic indicative of a rate at which information can be transmitted and received using the secure session; receiving facsimile signals and demodulating the received facsimile signals to produce facsimile data; encrypting the facsimile data; and, modulating the encrypted facsimile data for transmission over the secure session.
