SEC-TEL ENCRYPTION FEATURES
The technology is based around two internal tamper-proof
SmartCards. One delivers standard GSM services, whilst the other,
issued by a globally recognised Trust Centre, delivers powerful authentication
and encryption using established and open protocols. This is
known as the Crypto-Sim or Netkey card. These two technologies are
merged to create a unique, unbreakable cipher key for each and every call –
providing failsafe point-to-point authentication and unbreachable privacy from
one handset to another.
The Encryption-system employed is a hybrid mechanism, widely
used in high security products. The Sec-Tel phone
achieves full bi-directional authentication with the secret keys held securely
in, and never leaving, the safe environment of the Netkey card
A new IDEA or AES session key is randomly generated to start the
voice encryption process on the telephone before any speech is
transmitted. Sec-Tel devices negotiate the session key and type of
algorithm during connection set-up as part of transmission-path
authentication. At the end of the call, the session key is securely
discarded and not used again – all power is removed from the crypto module to
ensure that all data in respect of the call is destroyed.
Fully integrated HW module based on Intel Strong Arm Processor
and DVSI advanced speech Vocodor for superior speech quality.
