Audio Compression

Our highly optimized voice codecs support multiple network technologies and ensure that the call gets through even when network throughput is limited.

Transport Technology

GSMK CryptoPhones give you full flexibility to choose between either classical circuit-switched data (CSD) connections or Internet Protocol (IP) based communication links – thus offering you the full range of communication networks from analog telephone lines to 3G/UMTS high-bandwidth connections.

Encryption Engine

All GSMK CryptoPhones use the same encryption engine, which is a portable multi-platform cryptographic module that provides strong encryption, authentication, key exchange, message integrity verification, and secure memory abstraction services to GSMK CryptoPhone encryption products. Strong encryption algorithms and very long key lengths allow products that provide peace of mind today and in the future.

Software Architecture

The GSMK CryptoPhone architecture was designed to provide 360-degree protection not only against interception of confidential voice calls and messages, but also against attacks against the device itself. All GSMK CryptoPhone secure mobile phones feature a hardened operating system, secure storage, and voice and message encryption.
