The software converts your voice in real time to
encrypted data with a constantly changing mathematical formula. It uses
a large
asymmetric encryption key plus a changing session key that
replaces the encryption
every
second. The encrypted stream is subsequently deciphered
by the receiving unit, which converts it back to voice, providing end
to end protection for both voice and text messages, ensuring the
privacy of your communications.
On the other hand, if your calls travels unprotected (not encrypted)
within the
network, there are numerous ways to listen-in, as the unencrypted
signal travels from one cell to the next over microwave radio lines.
If
somebody manages to illegally intercept your cellular communication,
its content
will be protected by strong military-grade encryption even against the
most sophisticated interception
devices.
