Dubai, October 19 – Mobile security expert GSMK officially unveiled a new secure mobile phone, the CryptoPhone 500i, at GITEX Technology Week in Dubai today.

The CryptoPhone 500i succeeds the CryptoPhone 500, combining GSMK’s renowned voice and message encryption with true 360° mobile device security not found on any other mobile device.

Featuring version 2.0 of GSMK’s Baseband Firewall software, the phone not only offers strong end-to-end encryption and a hardened operating system, but also unique protection against over-the-air attacks with constant monitoring of baseband processor activity, baseband attack detection, and automated initiation of countermeasures. The next generation of the patented Baseband Firewall software also detects attempts to track a mobile phone user’s location by unmasking so-called “silent SMS messages” as well as paging requests channeled through the global SS7 network for inter-operator traffic exchange. Individual instances of the Baseband Firewall software running on a great many mobile phones can be networked to pass warnings to each other and allow mobile network operators to block SS7 requests using the GSMK Oversight SS7 IDS and firewall system that allows network operators to prevent such traffic from penetrating the network.

In addition to comprehensive protection of the device against attacks from outside, including GSMK’s hardened version of the Android operating system built from source code with granular security management and streamlined, security-optimized components and communication stacks, the CryptoPhone 500i continues to offer GSMK’s industry-leading voice and message encryption functionality. Featuring secure end-to-end encrypted messaging and voice over IP calls on any network, including 2G GSM, 3G, 4G, and Wireless LAN. GSMK CryptoPhone IP’s high transmission protocol efficiency with 4.8kbps bidirectional data streams allows the phone’s easy deployment even in the most challenging network environments and in remote areas of the world where only limited data throughput is available.

The GSMK CryptoPhone 500i is fully compatible with all GSMK CryptoPhone IP mobile, satellite and fixed-line encryption products, allowing secure end-to-end encrypted calls across network borders. It offers an unsurpassed level of mobile device protection previously unavailable on a commercial mobile phone platform.
