How it works

Basically SDV makes an automatic key exchange between peers that support such encryption protocol and secure the voice communication channel. In this way it provides the users the ability to verify that there is no man in the middle, by verbally comparing two strings. The two strings will be displayed on the caller phone and the called phone, and they have to be exactly the same.
The strings, that the caller and the called must compare to verify that the communication line is secure, are called Short Authentication Strings (SAS) and come from the PGP Word List (a list of words for conveying data bytes in a clear unambiguous way via a voice channel).

For usability purpose, the SAS can be verified only once, then each party can mark the other as “trusted”. In this way the parties do not have to verify the SAS in every calls. This great feature is provided by the key continuity feature of SDV.
