Preimage is a mathematical term. When we talk about our design, we use the + term "message" and say that it is usually H(data). The original reason to + call it preimage was that a Sigsum log computes H(H(data)), making the + message that is sent on the wire a "preimage" for the log's hash operation. + This terminology is not helpful. Let's just call this "message" on the + wire. A log uses it to compute checksum<--H(message). Checksum is logged. + 2. Verification key is also a mathematical term. When we talk about our + design, we use the term "public key" because it is more easily relatable. + 3. No other key has any capital letters. |
