Secure Voice

Are you concerned about who might be listening in to your calls? Privacy concerns are growing exponentially in recent days, and Secure Voice is the answer. Secure Voice provides a data-only voice solution to allow calling anywhere in the world, secured by the strongest available encryption, ZRTP. Your regular cell traffic is encrypted, but the encryption protocols are outdated and subject to downgrade attacks that can potentially let anyone with the proper equipment listen in on your calls. Using Secure Voice and the ZRTP protocol, your calls are fully encrypted from end to end, but are just as easy to use as a standard dialler. Combined with our other secure communication offerings (bundled as Secure Pack) Secure Voice is part of a complete protection package for your smartphone communication.

About ZRTP:

ZRTP does not require prior shared secrets, due to the creation of per session ephemeral Diffie-Hellman keys, combined with an initial share of a Short Authentication String (SAS). This means the creation of a trusted third party, such as a certificate authority, can be bypassed, and that the protocol is not reliant on a server of any kind. Key exchange is done during call setup, typically by sending each other a short authentication string, a series of numbers that ensure your call is protected. If the numbers do not match, the call is affected by a "Man in the Middle" attack, and you can end your call knowing a crisis was averted. Matching numbers ensure that your call is both encrypted and free of any external listener.

ZRTP goes further, by adding a second layer based on key continuity. Hashed key information is included in each call for use in the next. This ensures that unless the attacker was present for the initial key/SAS exchange, he is forever locked out of subsequent calls. Keys are destroyed at the end of each session, providing perfect forward secrecy. The result is an end-to-end protected conversation, without any delay or loss of quality.
