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.

kryptoCOM MILESTONES
 32‐char user authen.ca.on at kryptoCOM startup
 Lowest .me to establish a secure communica.on channel: circa 15 s.
 Best‐on‐market security standards compliance:
 AES256 bit algorithm with implementa.on compliant with FIPS‐197 and 256 bit key.
 Cryptographic hash by means of SHA‐256 algorithm compliant with FIPS‐180‐2.
 Key genera.on protocol which assures the destruc.on of the key at the end of the
connec.on.
