Advanced cryptography is a cornerstone of modern cybersecurity, employing sophisticated algorithms to secure data and communications. It goes beyond basic encryption to include techniques such as elliptic curve cryptography (ECC), which provides high security with shorter keys, making it efficient for devices with limited processing power. Quantum cryptography leverages principles of quantum mechanics, promising theoretically unbreakable encryption through quantum key distribution (QKD).
Homomorphic encryption is another cutting-edge method, allowing computations on encrypted data without needing to decrypt it, which is crucial for maintaining privacy in cloud computing. Zero-knowledge proofs enable one party to prove to another that a statement is true without revealing any other information, enhancing privacy and security in authentication processes.
Post-quantum cryptography is an emerging field addressing the potential threat posed by quantum computers, which could break many current encryption methods. This involves developing new algorithms that remain secure against quantum attacks, ensuring long-term data protection.
Blockchain technology employs cryptographic techniques to ensure the integrity and immutability of transaction records, supporting cryptocurrencies and other decentralized applications. Together, these advanced cryptographic methods are essential for protecting sensitive information in an increasingly digital and interconnected world

This week’s reading expounds a bit on last week’s content. We will cover certificates, public key infrastructure and key management. Answer the following questions and then discuss with your classmates:
- Please read the article on the risks of key recovery, key escrow and 3rd party encryption at https://www.schneier.com/paper-key-escrow.html. What do you think are the most important points made in this article, and why? Make sure to relate it to the course readings.
- Explain when a PKI is required. In your opinion, which of the three discussed trust models would be the easiest to use, manage and maintain across an enterprise organization, and why? Would this also be the most effective?
