Guarding the Gates w/ Nadim Kobeissi
Description
In the fast-paced world of cryptocurrencies, secure multi-party computation (MPC) and zero-knowledge proofs (ZKPs) form the bedrock of secure digital asset management. This talk delves into the insights gleaned from Cure53's audit of Coinbase's CB-MPC cryptographic library. Highlighting vulnerabilities ranging from high-severity elliptic curve subgroup attacks to subtle deviations in Ed25519 nonce generation, we'll unpack how these issues were identified, addressed, and resolved. Through this deep dive, attendees will gain valuable lessons on ensuring protocol correctness, preventing subtle cryptographic pitfalls, and maintaining security rigor in open-source cryptographic libraries.
