Isogeny Cryptography

Definition ∞ Isogeny cryptography is a form of post-quantum cryptography that relies on the mathematical properties of isogenies between elliptic curves. It offers potential advantages in terms of smaller key sizes compared to other post-quantum candidates, making it attractive for certain applications. This cryptographic approach is being developed as a defense against future quantum computing threats.
Context ∞ Isogeny cryptography is a prominent area of research in the post-quantum cryptography landscape, with ongoing efforts to standardize its algorithms. Current discussions focus on its performance characteristics, particularly key sizes and computational overhead, and its suitability for widespread deployment. Future developments will likely involve the finalization of standardization efforts and practical implementations in secure communication systems and digital signatures.
