The Theory of Cryptography Conference (TCC) 2026 is a flagship event organized by the International Association for Cryptologic Research (IACR). Hosted in the historic academic hub of Cambridge, UK, TCC focuses on the theoretical foundations of cryptography. Unlike more applied conferences, TCC is the premier venue for presenting paradigm-shifting research, foundational definitions, and the mathematical proofs that underpin modern secure communication.
The 2026 edition continues its tradition of rigorous peer review, featuring long-format presentations that allow for deep technical dives into complex cryptographic constructions. Key topics for the 2026 assembly include advancements in post-quantum security, zero-knowledge proof systems, and multi-party computation (MPC) foundations. Attendees will engage with the world’s leading cryptographers in an environment designed to foster collaboration and the exchange of radical new ideas. The program includes invited keynote speeches from Turing Award-level researchers, contributed paper sessions, and a vibrant social program within the University of Cambridge’s collegiate setting.
As digital infrastructures face increasing threats from quantum computing and sophisticated adversarial models, the theoretical work presented at TCC 2026 serves as the blueprint for the next generation of global security protocols. Whether you are a doctoral student or a veteran researcher, TCC offers a unique, high-concentration academic experience focused on the "why" and "how" of secure computation.
