CRYPTECH SCG is a cipher hardware device designed to enable secure communication between Cryptech mobile phones and normal desktop phones. This single device contains all the levels of communication for GSM, UMTS, Ethernet, PSTN and BLUETOOTH. All the encryption and encoding peripherals are designed to guarantee the most flexible, secure and powerful device.

The usage of the encryptor is really simple. You have only to put the CRYPTECH SCG between your phone and the communication line. Every time you dial a number with a special prefix, the call is automatically encrypted and sent to the Cryptech device of the receiver.

Different technologies are integrated into one device: encrypted communication over PSTN (fixed line traditional analogue), VOIP communication through encrypted Ethernet connection to the Internet, encrypted communication on line CSD, GSM VOIP communication encrypted Internet connection on UMTS. These features make CRYPTECH SCG unique, allowing users to communicate securely with any CRYPTECH device.

In the scheme below is possible to imagine the potentiality of communication of the CRYPTECH SCG.

Cryptech Secure Communication Gateway

CRYPTECH SCG enables secure communications through the fixed network PSTN or IP communication over Ethernet. The cryptographic functions are implemented into tamper-proof hardware. The encryption algorithm is AES 256-bit, but can be edited and modified under specific request. Encryption keys are managed in different ways depending on customers’ needs. Elliptic curve Diffie Hellman protocol can generate a key for each call (which is destroyed at the end of the communication), or a pre-shared key system can be used which is ideal for managing groups of users in a hierarchical fashion.
