Structured learning progressions that guide you from classical cipher basics to advanced quantum cryptography. Each path builds on the previous, with hands-on challenges and quizzes.
Start with the Caesar cipher and progress through substitution ciphers, transposition ciphers, and XOR encryption. No prior knowledge required.
Explore symmetric and asymmetric encryption, hash functions, digital signatures, and public key infrastructure used in modern security systems.
Master quantum key distribution (QKD), the BB84 photon polarization protocol, E91 entanglement-based encryption, and post-quantum cryptographic algorithms.
Apply cryptographic concepts to real-world network security scenarios, firewalls, intrusion detection, and defense strategies against cyber attacks.
