Secure Voice GSM

Are Your Cell Phone Conversations Secure?

Today, competitors, hackers, or governmental institutions can intercept any GSM cell call with relatively little effort. Our Secure Voice GSM Software is designed to encrypt your mobile phone calls on the fly, protecting you from eavesdropping and call interceptions.

Secure Voice GSM is a full duplex real time voice encryption solution, which allows you to talk and listen at the same time. The software is compatible with many Nokia handsets. No hardware modifications required!

Call authentication is made using an unbreakable RSA encryption based on a 1024 bit asymmetric key algorithm using a random key. The voice encryption is based on an ultra strong ARC4 algorithm and made using the RSA start session key. Your calls can never be violated by any third party, and that is guaranteed! Our software successfully passed highly advanced security tests performed by government experts and received a security certificate from the Israeli Ministry of Defense.

Everyday, hundreds of people (politicians, lawyers, police and anyone else who recognize the dangers of having confidential information fall into the wrong hands) use Secure Voice GSM software.

Secure your right to privacy. Don´t give data spies, competitors, detectives, and government agencies a chance! By using our Secure Voice GSM software you can be 100% sure that all your conversations are 100% encrypted and confidential!

Fully compatible Nokia cell phones:
SV GSM is fully compatible with the following Nokia mobile phones: N71, N73, N73 Music Edition, N80, N81, E61, 5228, 5230, 5230 Nuron, 5530 XpressMusic, 5233, 5235 Ovi Music Unlimited, 5250, 5800 XpressMusic, Nokia N97, Nokia N97 mini, Nokia X6.Please Note: The Data Call (CSD Line) must be enabled on your SIM card and the phone must be used on a GSM network (UMTS, 3G, CDMA network standards are not currently supported by our Secure Voice GSM). These services may not be available via all operators, and may require separate subscription. It is the customer's responsibility to ensure that CSD services are available with their preferred GSM operator.
Secure Voice GSM does not use your cell phone's voice channel but it sends the encrypted voice through the data channel of the cell phone. This brings also the advantage that an attacker who usually monitors the voice channel will not even realise you are communicating with other people! The call costs for encrypted calls are exactly the same as for standard calls. Guaranteed protection from any kind of spy cell phone interceptor. Additional measures are implemented into the Secure Voice GSM software to automatically detect and prevent man-in-the-middle attacks.
Please Note: The voice encryption software must be installed on each separate handset to create a 100% guaranteed secure connection. A secure encrypted connection cannot be created between a cell phone which has software installed and a cell phone which does not have software installed.

Your SMS is NOT Secure, But Help is at Hand

Current standard SMS technology is not secure - meaning it can be intercepted along the transmission path at multiple locations: aggregators, carries, infrastructure providers, or tower operators. If you are looking for securing your SMS (text message) traffic, you can stop your search here! Secure SMS solution is ideal for both individuals and businesses that care about their privacy. Secure SMS fully protects you from commercial espionage, governments, mobile phone companies, and any third parties (using GSM interception systems) who seek to discover your sensitive information or private correspondence. All your text messages transferred over the GSM or CDMA networks will be encrypted (end to end encryption).
