What do we mean by an insecure medium? Well, in some dictionary or another, under the definition of “insecure medium” should be a picture of the Internet. The world is evolving towards interconnecting every computer, and people talk about connecting household appliances as well, all into some wonderful global internetwork. How wonderful! You’d be able to send electronic mail to anyone in the world. You’d also be able to control your nuclear power plant with simple commands sent across the network while you were vacationing in Fiji. Or sunny Libya. Or historic Iraq. Inside the network the world is scary. There are links that eavesdroppers can.
