Course Contents

• Confidentiality via symmetric-key encryption (DES, 3DES, AES), block cipher modes, and asymmetric-key encryption (RSA, ECC)
• Integrity and Authenticity via cryptographic hash functions (SHA-1, SHA-3), message authentication codes (HMAC, CMAC), and digital signatures (RSA, ECDSA)
• Random Number Generation, including true random number generators (TRNGs) and hardware generators (e.g., Intel DRNG)
• Cryptographic Key Distribution, including Diffie–Hellman key exchange, Key Distribution Centers (KDCs), Certificate Authorities (CAs), and Public Key Infrastructure (PKI)
• Human Authentication, including passwords and password-based schemes
• Cryptographic Authentication, including challenge–response, one-way, two-way (mutual), and mediated authentication
• Case Studies, involving Kerberos (Active Directory) and the TLS protocol
• Recent Trends in Cryptography, including cryptocurrencies, quantum cryptography, zero-knowledge proofs, and secure multiparty computation
• Hands-on Labs: All important theoretical concepts were reinforced through weekly hands-on labs, using tools such as OpenSSL, Wireshark, Hashcat, Ent, rngtest, and Qualys SSL/SSH test, along with Apache server configuration and custom Python scripts.
