Chaum mixes

The KIIS Network is a network of radio stations owned and operated by the Australian Radio Network. Formerly branded as the Mix Network, the network rebranded as the KIIS Network in 2015 following the relaunch of KIIS 101.1 Melbourne.

Mix networks are routing protocols that create hard-to-trace communications by using a chain of proxy servers known as mixes which take in messages from multiple senders, shuffle them, and send them back out in random order to the next destination (possibly another mix node). This breaks the link between the source of the request and the destination, making it harder for eavesdroppers to trace end-to-end communications. Furthermore, mixes only know the node that it immediately received the message from, and the immediate destination to send the shuffled messages to, making the network resistant to malicious mix nodes.
