Quantum Cryptography Explained

Subject Area

Digital Literacy and Computer Science

Grade(s)

7, 9, 10, 11, 12

Overview

With recent high-profile security decryption cases, encryption is more important than ever. Much of your browser usage and your smartphone data is encrypted. But what does that process actually entail? And when computers get smarter and faster due to advances in quantum physics, how will encryption keep up? This video can be played during a lesson on identifying common methods of securing data.

Unpacked Content

UP:DLCS18.HS.29

Vocabulary

  • compression
  • encryption
  • metadata

Knowledge

Students know:
  • that when a file is altered in any way, changes may be seen in the file metadata.
  • compression and encryption are two methods used when sharing data.

Skills

Students are able to:
  • explain the roles of compression and encryption.
