This paper briefly describes the effectiveness of voice encryption in securing the confidentiality of sensitive public safety radio traffic.
Key points identified in the use of voice encryption include: (1) unencrypted public safety voice transmissions can be intercepted, abetting criminal activity, thwarting public safety efforts, and endangering the public and public safety personnel; (2) voice encryption helps ensure that voice transmissions can be accessed only by authorized personnel; (3) voice encryption adds complexity and cost to public safety voice networks; and (4) effective management is essential to implementing an encrypted voice network successfully. Public safety land mobile radio systems are vulnerable to eavesdropping and can easily be exploited by criminals. To ensure that sensitive information is shared only among authorized individuals or organizations, public safety operators need to ensure the confidentiality of sensitive radio traffic which can typically be accomplished through voice encryption. However, adding encryption to a radio system involves securing and transmitting the message and managing cryptographic keys. 2 notes
