A bonus challenge explores threshold signatures utilizing OR proofs for multi-signature wallets, demonstrating superior applications of zero-knowledge composition. This problem set explores high-assurance cryptography and formal verification from matter 2.5, overlaying design-level safety, implementation safety, and practical computer-aided cryptography. In design-level security, you will analyze trade-offs between symbolic (ProVerif) and computational (CryptoVerif) verification approaches and tackle software choice for protocols combining TLS 1.3 with post-quantum mechanisms. The implementation security section examines constant-time programming challenges, compiler optimizations that break security guarantees, and hardware-level timing assaults. The assignments hold returning to the gap between what verification proves and what deployment requires.

This topic explores Fully Homomorphic Encryption (FHE), a cryptographic primitive that permits arbitrary computations on encrypted data without ever decrypting it. The matter traces the historical past of FHE from Rivest, Adleman, and Dertouzos’s 1978 open downside through Craig Gentry’s landmark 2009 construction primarily based on best lattices, which introduced the bootstrapping technique to manage ciphertext noise development. We’ll analyze the core technical challenge of noise accumulation in lattice-based ciphertexts and the way bootstrapping (homomorphically evaluating the decryption circuit) allows limitless computation depth. The topic covers sensible concerns together with parameter choice, noise budgeting, SIMD-style batching through the Chinese The Rest Theorem, and the significant computational overhead that continues to be a barrier to widespread adoption. We’ll look at real-world functions of FHE including privacy-preserving cloud computing, encrypted database queries, safe machine studying inference, and confidential data analytics, analyzing deployments by firms like Google, Microsoft, and IBM.

Pseudorandom features (PRFs) lengthen this by creating massive virtual dictionaries mapping inputs to pseudorandom outputs, permitting parties with a shared secret to derive unlimited pseudorandom knowledge. Pseudorandom permutations (PRPs), additionally known as block ciphers, present both forward and inverse operations indistinguishable from random permutations. We’ll study key constructions including https://www.mlb4s.com/category/network-protocols-and-security GGM (building PRFs from PRGs), the Feistel network (building invertible PRPs from non-invertible PRFs), and the PRF-PRP switching lemma that permits interchangeability in safety proofs.
Each group of one to 3 students is predicted to pick one (or, if you’re feeling adventurous, at most two) project subjects and work on them throughout the complete course. Throughout every project, you’ll experiment with real-world libraries, and even simulate attacks or vulnerabilities to understand why sure safety practices are necessary. These tasks may also assist you to turn out to be comfy with relevant instruments and environments, together with formal analysis tools. Problem units might be assigned periodically throughout the semester to strengthen and deepen your understanding of the lecture material. Every set will embrace a variety of exercises—some targeted on theoretical proofs and problem-solving, others requiring short coding tasks or computational experiments. These assignments are designed to bridge the gap between summary cryptographic ideas and their concrete applications.
