You
have two freeware versions available for download.
• Cellular
and landline calls with 75 seconds of conversation for each
call.
• Only
landline calls with unlimited time for each call.
Our
freeware versions have in common:
• Allow
unlimited calls.
• Have
the same security as our commercial version (256 bits AES
CBC mode encryption, 571 bits ECDH Koblitz).
• Allow
3 licenses for each company or government.
We
are using an advanced new generation of cryptography,
you can see what an extensive article from the NSA (USA
- National Security Agency) says about this technology:
"Elliptic Curve Cryptography provides greater security
and more efficient performance than the first generation
public key techniques (RSA and Diffie-Hellman) now in
use".
Our
secure phone technology uses two steps to encrypt the
voice:
1.
Key exchange (using a key exchange algorithm).
2. Voice Encryption (using a symmetric algorithm).
These
two steps are important for the product security and we
can compare these process with a door and its key. No
matter how strong is the door (voice encryption), if you
don't care with its key security, you won't keep it locked
against intruders.
Below we compare different key exchange technologies,
at the left we have the key exchange technologies, at
the right we have their securities.

Our near competitor (#4) have a 160 bits
security. Each bit increased in the symmetric encryption
key size doubles the difficulty to break the encryption,
for example, from 160 bits to 161 bits you multiply by
2 the difficulty.
Comparing the encryption #4 with our encryption (#5),
we are 1,000,000,000,000,000,000,000,000,000,000 times
more difficult to break, you can read more about in our
Cryptography page.
As
important as the symmetric encryption algorithm is the
Encryption
Mode of Operation, we are using the strong CBC mode.
For example, no matter is strong your 256 bits symmetric
algorithm, do you know if your product uses a weak encryption
mode of operation, the attacker can discover when you
have silence (nobody talking) in the line?, or even discover
you repeating a word in your conversation?
With our product you expand your cellular
smartphone/pocketpc phone to work as a secure cellular/landline
phone. Adding a SDIO or compactflash modem to your PocketPc,
in the same equipment you will be able to do cellular
and landline calls.
SecVoice
Secure Phone doesn't have any kind of backdoor, because
our country (BRAZIL) laws allow us to develop this kind
of security products with the best encryption technology
available, and we garantee under contract.
