GSMK CryptoPhone secure mobile, landline and satellite products offer trustworthy 360-degree protection for encrypted communications across network borders:

Voice Encryption

GSMK CryptoPhones are the only secure telephones on the market that come with full source code published for independent security assessments. They feature the strongest and most secure encryption algorithms available today as well as the longest key lengths available on the global market, thereby offering true strategic security and peace of mind today and in the future. GSMK CryptoPhone secure mobile, fixed-line and satellite phones use latest-generation voice codecs and are fully compatible so that encrypted calls can be made across network borders – mobile to mobile, mobile to fixed-line, fixed-line to satellite, all with seamless interoperability.

Secure Messaging

All GSMK CryptoPhone secure mobile phones feature voice as well as SMS message encryption. With a 4096-bit Diffie-Hellman key exchange and 256-bit AES and Twofish symmetric encryption, they reliably protect confidential calls and messages without any compromises in usability. Secure international messaging comes standard with special features like self-destructing “Eyes Only” messages.

Mobile Device Security

A truly secure communication device must not only protect its communication links, it must also be able to withstand attacks against the device itself. To achieve this, all GSMK CryptoPhone secure mobile phones are based on a “hardened” operating system with granular security management and streamlined, security-optimized components and communication stacks. The hardened operating system reliably protects the device against outside attacks, thus offering true 360-degree protection when it counts most.

GSMK CryptoPhone secure mobile phones also come with an encrypted storage system for contacts, messages, and keys. Smart folders protects confidential data against unauthorized access should the phone be lost or stolen.
