COMP61411 Cryptography syllabus 2017-2018
Cryptographic techniques today lie at the heart of the strategies used to protect users' data from unauthorised access. They come into their own particularly when data has to be transmitted across unreliable and unprotected networks.
The course aims to give students a good appreciation of cryptographic techniques, as they have arisen historically, and as they are used today.
- Early cryptography: permutations and substitutions, Vignere, Vernam, one time pads, etc.
- Rotor machines: Enigma and its relatives.
- Case study: Marian Rejewski and the breaking of the German Enigma.
- Modern cryptography, secret key: block cyphers, DES, AES, etc.
- Modern cryptography, public key: Diffie-Hellman, RSA, elliptic curves.
- Message authentication, hash functions.
- Quantum cryptography: quantum key distribution in practice.
