Eavesdropping on the line:
Secure electronic communication is becoming increasingly important. In recent
years, quantum cryptography has been investigated as a means of detecting
eavesdroppers on private lines. When quantum mechanical processes are used
to establish the 'key' used for encryption and decryption, any eavesdropping
during transmission leads to an unavoidable and detectable disturbance in the
received key information. This technique has been demonstrated to be effective
on standard communication lines between two users, but Paul D. Townsend now
introduces a practical scheme for a multi-user network. This work demonstrates
the technical feasibility of quantum cryptography for practical applications.
