The intuition behind elliptic curve digital signatures (ECDSA) This article explains how the ECDSA (Elliptic Curve Digital Signature Algorithm) works as well as why it works. We will incrementally "rediscover" the algorithm from first principles in this tutorial. Prerequisites We assume prior knowledge of Elliptic Curve Arithmetic Elliptic Curve Arithmetic in Finite Fields Digital Signature... |

One weird hobby of mine is reasonable properties of cryptographic schemes that nobody promised they do or don't have. Whether that's invisible salamanders or binding through shared secrets, anything that isn't just boring IND-CCA2 or existential unforgeability is just delightful material to construct vulnerabilities with. Normally, with a signature scheme, you have the public key... |

There is, at the time of this writing, an ongoing debate in the Crypto Research Forum Group (CFRG) at the IETF about KEM combiners. One of the participants, Deirdre Connolly, wrote a blog post titled How to Hold KEMs. The subtitle is refreshingly honest: "A living document on how to juggle these damned things." Deirdre... |
