Overview:

Unencrypted communication over the Internet works a lot like sending a postcard: it can be read by anybody along the delivery route. Communication is routed through intermediary computers and systems, which are connected to many more computers and systems. Encryption, or encoding information so it appears scrambled to anyone who doesn’t know the key, is a way to wrap a postcard in an envelope. While it can never be 100% secure, stronger encryption makes it harder for people to get to the contents.

The lesson elements in this module teach students about the privacy principle “Communication over a network, unless strongly encrypted, is never just between two parties”. They are designed to be independent and flexible, so you can incorporate them into any size lesson plan. Student resources are available at https://teachingprivacy.org/someone-could-listen/. 

Summary of Learning Objectives: Students can articulate how the multi-step, multi-party pathways of networked communication affect users’ privacy; students can identify and use more secure communication options.

Target Age: High school, college undergraduate.

Learning Objectives: 

  1. Students can describe how intermediary devices, and the services that provide them, are involved in transmitting information from point A to point B on the Internet.
  2. Students can explain how the interconnected, many-layered structure of the Internet affects the security and privacy of online communication.
  3. Students can identify the difference between a private network and a shared network and can describe some of the potential risks of using a shared network.
  4. Students can describe how encryption decreases the chances of outside parties infiltrating private communications and accessing private information.
  5. Students can explain why their security depends (in part) on their own decisions and behavior.
  6. Students can give some examples of common encryption protocols, identify what layer of an electronic communication each of those protocols protects, and describe how they would verify that those protocols were being used.
