FAQ Basics

1. Basics

1.1 What are the Secuvoice parts?

Secusmart combines secure hardware-based encryption and certificate-based subscriber authentication with easy handling and brilliant voice quality. Secuvoice consists of a Nokia Eseries or Nseries mobile phone, a microSD card with integrated crypto controller and the Secuvoice software.

1.2 Who ist the Secuvoice target market?

Secusmart targets CxO´s: high-level executives, administration, large and medium-size enterprises.
Why should executives and managers use encrypted communication?
Executives and managers increasingly become targets of industrial espionage. Unique knowledge bases are getting smaller, product cycles are getting shorter while competition is increasing. Information about corporate strategies, contract negotiations or innovations are important assets for each enterprise, which must be protected.
Secuvoice is relevant for all who want or need to make and receive secure calls.

1.3 How does one install Secuvoice?

It is a plug-and-play application: Just insert your Secusmart Security Card into the memory card slot of your mobile phone. The Secuvoice application will be installed automatically. After a few seconds when installation is complete you can use Secuvoice to make secure calls.

1.4 Which mobile phones are supported by Secuvoice?

Secuvoice functions on the latest Nokia high-featured business phones, the E-Series. Selected Nokia N-Series multimedia phones are also supported. Secuvoice will also run on future models of Nokia E-Series and N-Series, given they have a microSD card slot.
With Secuvoice you are not tied to one particular phone that could be outdated in a year or two. If you wish to use a new phone, just transfer your Secusmart Security Card into your new phone and your calls remain secure.

1.5 Is it still possible to make and receive normal telephone calls?

Secuvoice enables you to make and receive secure voice calls on your Nokia mobile phone. Secuvoice is complementary to the original functions of your mobile phone, so you can still make and receive normal voice calls, browse the web, run PIM (personal information management) applications and stay connected to your corporate push-email service while on the move.

1.6 How easy too use Secuvoice?

Make and receive secure calls in the same way you would do normal calls, once you are in the Secuvoice application. Just press the Secuvoice button to access the application. Within the Secuvoice application you have access to your secure contacts, you can manage missed, received and dialled secure calls, or simply dial the number of a person you wish to call securely.

Secuvoice seamlessly integrates into the proven Nokia user interface. You don’t have to relearn how to manage your secure calls.

1.7 What is the speech quality of Secuvoice?

When it comes to speech quality, you won’t be able to tell the difference between a secure call and a normal GSM voice call. Secuvoice provides uncompromised speech quality by using the original GSM-AMR codec for speech compression.
Secure calls remain clear and intelligible even in noisy and reverberant situations, as Secuvoice deploys advanced Nokia DSP technology for noise reduction and acoustic echo cancellation.

1.8 How does Secuvoice deal with security relevant data?

Secuvoice leaves no footprint on the memory of your phone. The application and all sensitive data, like your Secure Contacts and the history of your missed, received and dialled Secure Calls (Call Log), are stored in the Secusmart Security Card.
If you wish to turn your secure phone back into an ordinary phone, just remove the Secusmart Security Card. It is impossible for others to discover that Secuvoice was ever on your phone. If you want to re-secure your phone, just reinsert the Secusmart Security Card.

1.9 Does Secuvoice affect the battery life?

Secure Calls with Secuvoice do not drain the battery of your mobile phone any faster than normal GSM calls. Both crypto and speech processing runs on the hardware, on the Secusmart Security Card.
Speech processing of secure calls runs through the same digital signal processor (DSP) that is used to process speech during normal GSM calls.
Parallel encryption and decryption of uplink and downlink speech data runs entirely on the high-speed AES co-processor integrated in the crypto controller inside the Secusmart Security Card.

1.10 Are any contract changes required for Secuvoice to work?

Secuvoice relies on non-transparent GSM-CSD service for secure speech transmission. In contrast to the sparse coverage of transparent GSM-CSD or 3G services, non-transparent CSD is available wherever standard GSM voice service is available.
