kryptoCOM overview

kryptoCOM is an Anti Tapping mobile phone (based on Windows Mobile 6.x) for encrypted secure GSM calls.

kryptoCOM uses the CSD channel (which enables data/FAX traffic) to establish encrypted mobile communications on GSM networks.

The technology used by kryptoCOM relies on end2end secure GSM encryption with AES256 bit cipher key generated with Elliptic Curves Diffie-Hellman (ECDH) 517 bits (equivalent of Diffie-Hellman with 15.000 bits key); a new key is being generated for each call.

kryptoCOM is actually available on HTC Touch Viva GSM.
