Symmetric-key Cryptography. - The syntax of private-key encryption. The classical ciphers. Elementary cryptanalysis and frequency analysis. - Perfect secrecy. The one-time pad. - A computational ...

We will cover classical ciphers and cryptographic methods such as DES, 3DES, Feistel, AES, RC5, and Modern Public Key cryptography (e.g.RSA, Diffie-Hellman, ECC) and PKI ( Public Key Infrastructure).
