| | | | | Digital Signatures The digital signature (sometimes called an electronic signature) isn't a literal digitalized signature. In layman's terms, it is a procedure that guarantees the integrity and the authenticity of digital documents and messages. The name of a digital signature comes from the analogy with the handwritten signature of a paper document. Everyone knows that there is a lot of paperwork in the world of business. And, where there is paperwork, there is a lot of validation, approvals, etc. | |

| | | | | The elliptic curve digital signature algorithm (ECDSA) is a common digital signature scheme that we see in many of our code reviews. It has some desirable properties, but can also be very fragile. For example, LadderLeak was published just a couple of weeks ago, which demonstrated the feasibility of key recovery with a side channel [...] | |

| | | | | 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... | |
