In SIT281 students will learn the fundamental mechanisms of classic and modern cryptographic systems, which span from Caesar cipher of Roman times to Advanced Encryption Standard (AES) cipher invented in the early 21st century. Students will encrypt and decrypt messages by using modern symmetric encryption schemes including DES and AES, stream ciphers used in mobile phone networks and pay TVs, as well as the most well known public key cipher RSA. The unit will also provide students the opportunity to explore the cryptographic applications.
