Encrypted mobile blocks eavesdroppers
A new handset from ST Electronics uses a 56-bit key for voice encryption and decryption, although both participants in a conversation must be using the model. ST Electronics has taken the wraps off a new encrypted cellphone that thwarts high-tech eavesdroppers. Designed for highly secured voice communications, the Mirage handset is targeted at senior executives and uses a 56-bit key for voice encryption and decryption. Two units of the Mirage are required to have a secure conversation.
Encrypted mobile phones make it harder for eavesdroppers to decode conversations using specialised equipment. Other companies including CryptoPhone, Siemens and Motorola have released similar products.
