Information is power.
Even before the first written word, the need to safeguard information created an ongoing evolutionary battle between codemakers and codebreakers .
Cryptology is the study of secret writing such as codes and ciphers. Beginning with early techniques for creating secret writing, such as the Caesar shift, monoalphabetic substitution, and the Vigenère cipher, students then move on to learn about modern techniques including digital encryption and RSA public key cryptography. Discussions about the vulnerabilities of each encryption system enable students to attack and decrypt messages using techniques such as frequency analysis and cribbing. Students apply what they learn to encrypt and decrypt their own secret writing.

Your grade will be calculated based on your completion and performance on the following:
(quizzes, tests, final exam)
Scientific or graphing calculator
Student grades are based on the total number of points earned using the following scale:
A = 90-100%
B = 80-89%
Group Challenges and
C = 70-79%
D = 60-69%
F = below 60%
