Cryptography is a fundamental skill to cybersecurity!

Cryptography is what keeps our systems and data secure. Without it, all of our information is at risk.

This class to designed to give you a strong background in cryptography further enhancing you knowledge and skill in this key field making you even more valuable in the cybersecurity marketplace.

With quantum computing and quantum cryptography emerging on the near-term horizon, a strong background in cryptography will help your organization prepare and keep your data secure.

If you are a cybersecurity professional or manager, you will want to attend this training!

1. Foundations & Mathematical Background

Probabilistic and computational security

Number theory basics (modular arithmetic, cyclic groups)

One-way and trapdoor functions

2. Symmetric-Key Cryptography

Stream ciphers (One-time pad, RC4)

Block ciphers (DES, AES, Feistel networks)

Block cipher modes (CBC, ECB, CTR, OFB)

Attacks: brute-force, linear, differential cryptanalysis

3. Message Authentication & Integrity

Message Authentication Codes (HMAC, CBC-MAC, PMAC)

Collision-resistant Hash Functions (SHA family, Merkle-Damgård)

Authenticated encryption modes (GCM, CCM)

4. Public-Key Cryptography

Arithmetic in finite groups, cyclic groups

Diffie-Hellman key exchange, CDH/Discrete-log assumptions

RSA and El-Gamal encryption systems

Security notions: semantic security, CCA security

5. Digital Signatures

RSA signatures, applications

Hash-based and elliptic curve signature schemes (ECDSA, etc.)

Certificates and PKI infrastructure

6. Advanced Protocols

Password protocols, challenge-response, salts

Secure key exchange protocols (TLS, SSL, authenticated key exchange)

Zero-knowledge proofs and commitment schemes

7. Modern & Emerging Topics

Post-quantum cryptography (lattice-based, hash-based schemes)

Quantum attacks on classical systems

Homomorphic encryption and applications

8. Practical Applications

Cryptographic implementation pitfalls (side-channel attacks, real-world failures)

Case studies: Secure messaging, disk encryption, cryptocurrencies

Secure software engineering: protocol design, trusted setup, code audits

9. Attacks and Defenses

Cryptanalysis case studies

Implementation vulnerabilities (padding oracle, timing attacks, etc.)

Attacks against protocols and key management
