| Description:
| Aims:
To introduce students to the techniques, tools and pitfalls of cryptography (including authentication etc.).
Learning Outcomes:
1. Students will understand the basic mathematics behind private-key and public-key cryptography;
2. Students will be able to describe several well-known techniques for cryptographic security and authentication.
Skills:
Application of Number (T/F, A), Problem Solving (T/F).
Content:
Introduction to the problem: security, privacy, authentication, repudiation, revocation. The key distribution problem: public vs private keys. The mathematics of cryptography: Fermat-Euler Theorem, structure of finite fields and elliptic curves. Cryptographic algorithms: Diffie-Hellman, RSA, El-Gamal. Cryptanalysis: discrete logarithms, factoring. The Coppersmith attack. Elliptic Curve analogues. Private-key algorithms: DES, 3DES and AES. Common hashing algorithms: MD5, SHA-1. Characteristics of safe keys.
Using cryptography: digital signatures: how to find the public key.Repudiation and revocation, examples in practice: PGP, digital certificates.
