Subject Description
This subject develops the skills and knowledge necessary to identify and address security problems in a variety of simple communication models. Topics covered include: Classical cryptology, Modern secret key cryptography including block (DES, AES) and stream ciphers (RC4), security properties (authentication, integrity, confidentiality, availability), public key cryptography (knapsacks, RSA, Rabin, Elgamal), digital signatures (RSA, DSS, Elgamal) , hashing (birthday paradox, Merkle-Damgard construction), MACS's, Key management (PKI, certificates, key establishment/exchange/transport, Diffie-Hellman), Identification protocols, Privacy preserving (mix-nets), Secret sharing. Applications studied include some of: email security, SET, E-payment, E-voting, Fair exchange.

Subject Learning Outcomes
On successful completion of this subject, students will be able to:
1. Explain and apply fundamental cryptographic principles and terminology.
2. Classify and distinguish cryptographic algorithms in terms of their cryptographic characteristics and services provided.
3. Select and apply appropriate fundamental cryptographic building blocks, such as encryption, hashing and authentication, based on a critical analysis of an application scenario.
4. Implement cryptographic algorithms in Java or C/C++.
5. Describe and demonstrate the use of some of the mathematics underlying modern public key cryptography.
6. Assess and contrast the security of given scenarios, and justify the need for additional security as appropriate, taking into account the required cryptographic properties and such factors as efficiency.
7. Analyse implementations of cryptographic algorithms.
8. Explain the role of, and illustrate and usage of, cryptography in a range of applications.
9. Discuss the significance of cryptography in modern society.
10. Read and interpret aspects of cryptographic technical documents such as RFC’s and standard’s documents.
11. Present and rewrite material demonstrating competence in the above outcomes.
12. Apply statistical cryptanalysis.
