<p>At around 2,000 (US$2800) each, the secure smartphones that SecuSmart showed at Cebit last year were out of reach of many businessesalthough three governments have since bought them to secure mobile phone calls between senior officials, according to CEO Hans-Christoph Quelle. Now the company has developed a less expensive and more flexible system intended for the enterprise, and has extended the reach of its mobile system to secure VOIP calls on desktop phones.</p><p>The SecuSuite smartphone security system is built on the Balance feature of BlackBerry OS 10, which separates business and personal apps and data into two partitions. SecuSmart uses special SD cards containing a cryptographic engine and a keystore to further secure the data in the business partition, and to encrypt voice and data communications made from that partition.</p><p>Its new fixed-line product relies on the same SD cards, central key infrastructure and SIP servers used by the smartphone system, but now works with modified desktop VOIP phones from Tiptel and Snom. The phones have a slot for the SD card encryption engine, and additional software that manages the card, and indicates when a call is secured. They will allow government officials to place secure VOIP calls between premises that are not themselves secure.</p><p>SecuSmart and its partners have not yet set a price for the new desktop phones. Quelle said it will be less than the price of a BlackBerry Z10 equipped with the secure SD card, but not hugely so.</p><p><a href="http://www.pcworld.com/article/2108640/secusmart-puts-its-blackberry-encryption-chip-to-work-on-the-desktop.html">Keep reading...</a></p>
