Abstract
An apparatus includes an audio-sensor inhibitor configured to inhibit detection of sound by an audio sensor of a communication device, and a secure communication interface coupled to the audio-sensor inhibitor, the secure communication interface being configured to transmit encrypted audio data from the secure communication interface to the communication device, wherein the communication interface generates audio data using a secure-interface audio sensor, and generates the encrypted audio data by encrypting the audio data using a cryptographic module.
