Cryptography – Cracking the Code – Solve the Secret Messages!
We will encrypt plain text and allow others to decrypt the cipher text. We will provide three one-hour lessons as well as many other resources.
Cryptography was started way before computers and cyber security. In fact, the first recorded use of written cryptography was 1900 BC. In a book by Liza Mundy, we find that women were hired to be cryptographers in WWII– deciphering text sent between Japanese invaders. These female cryptographers work played a crucial role in ending World War II.
Modern cryptography uses sophisticated mathematical equations (algorithms) and secret keys to encrypt and decrypt data. Today, cryptography is used to provide secrecy and integrity to our data, and both authentication and anonymity to our communications.
Cryptography combines math, computing, and history.
