Security Advice
Your CryptoPhone is a Communication Security (COMSEC) device. It can
only be regarded as secure as long as you have
permanent and unin-
terrupted physical control over the CryptoPhone. Once an adversary
could have gained temporary physical possession of the CryptoPhone,
it must be regarded as compromised. There is a variety of potential
methods that would allow an adversary to listen into your calls after
he manipulated the CryptoPhone and gave it back to you. Keep the
handset with you securely at all times. You should take it with you to
the bathroom, put it beside your bed when you sleep and not leave it
alone in the hotel room.
If you have »lost« the CryptoPhone and »find« it back again, it has to
be regarded as compromised. Never lend your CryptoPhone. Major in-
telligence agencies are known for a wide variety of high-tech manipu-
lation methods that are impossible to detect without a massive scien-
tific effort (several months of analysis at the cost of several 100.000
Euros per device). If in doubt and your security depends on it, consider
purchasing a fresh unit.
