Students will be able to:
Explain the difference between asymmetrical and symmetrical encryption
Explain how computing tools can be used for decryption
Identify why Caesar Cipher and Random Substitution Ciphers are not adequate for most encryption needs
In this lesson students explore two different encryption widgets: The Caesar Cipher Widget and the Random Substitution Cipher. Afterwards, students watch a video that reviews these types of encryption and introduces a new concept: public key encryption.
