sphone: security in mind

Posted on 01 July 2012 by Pierre Picard

Protecting mobile communications with a government-approved solution

The security of mobile communications is a constant, even growing concern for businesses and public institutions alike. Although solutions already exist to ensure the security of data on mobile devices, voice and text communications remain vulnerable. To tackle this, Bull’s subsidiary Time Reversal Communications has developed sphone, the first mobile phone system with native security features offering integral protection against the theft of the device itself, tapping of voice or text communications, and break-in and theft of personal data.

sphone – approved and used at government level in France – is part of a holistic communications solution including e-mails, intranets and file servers. This means security can be managed in an integrated way by the organization itself and does not depend on third parties. The secure communications carried out using sphone are totally controlled, hosted and administered by the organization’s own IT and security departments. The system also includes a Device Management solution that enables terminals to be administered remotely. sphone was jointly developed with ERCOM, a company specializing in secure communications and using the Cryptosmart™ certified security solution.

Sphone can be integrated with existing information and security systems
The sphone solution includes a central system consisting of a secure gateway and a Card Manager, and uses a Key Management Infrastructure. The secure gateway enables all the mobile devices on the system to connect to each other, as well as with the organization’s servers and central switchboard (PBX). The Card Manager hosts (or interfaces with) the Certification Authority and administers user security.

sphone, PCs and Internet boxes incorporating a Cryptosmart™ Card run critical security operations.
sphone requires a standard SIM card, with a Voice + Data subscription. Voice is used for unscrambled calls, whereas the Data service is used for secure calls (VoIP). An Internet connection is required for the gateway. Optionally, interconnections with the internal network (LAN) are needed to access enterprise servers and the PABX/IPBX for the fixed telephony system.
