Crypto phones are mobile telephones that provide security against eavesdropping and electronic surveillance.The interception of telecommunications has become a major industry. Most of the world's intelligence agencies and many private organisations intercept telephone communications to obtain military, economic and political information.
The price of simple mobile phone surveillance devices has become so low that many individuals can afford to use them.Advances in technology have made it difficult to determine who is intercepting and recording private communications.
Crypto phones can protect calls from interception by using algorithms to encrypt the signals. The phones have a cryptographic chip that handles encryption and decryption. Two algorithms are programmed into the chip: A key-exchange algorithm for the key agreement protocol and a symmetric-key algorithm for voice encryption.
An international electronic security expert from the Gold Coast Mr.Les Goldsmith is making "cryptophones", the phone also believed to have been used by WikiLeaks founder Julian Assange to avoid detection by government spies, use encryption technology to block hackers.
Mr Goldsmith said his company had supplied cryptophones to government officials in Australia and overseas, corporatec executives wanting to keep trade secrets and even, unwittingly, to criminals trying to avoid police phone taps.
The mobile phone interceptors or fake "base stations" able to be carried in brief cases, more individuals and companies were buying cryotpophones to keep their calls confidential.
He said "ESD is currently the largest provider of security telephony across Asia".
Goldsmith admits that the balance between law enforcement agencies being able to do their job and an individual's right to privacy is precarious.
"When we sell the products to secure calls we're doing it under the understanding that person purchasing the product won't use it for a criminal act," he said, adding that there are currently no restrictions on people purchasing encrypted phones within Australia.
"It's something when we introduced the product we did ask law enforcement what was done and we were told that scrutiny of [phone calls] would be an invasion of privacy," he said. "There have been cases before where individuals have in fact purchased crypto phones and then used them in activities that are not legitimate."
