It is not a survey; it is the specific, working understanding of "Reading: Merkle, Secure Communications Over Insecure Channels" that the rest of the course assumes you carry forward.
- 01Define Reading: Merkle, Secure Communications Over Insecure Channels in the precise sense used across Cryptography Foundations.
- 02Recognize when Reading: Merkle, Secure Communications Over Insecure Channels is the correct lens for the situation in front of you, and when it is not.

A founding paper. That single sentence is the whole lesson in compressed form. The rest of the reading unfolds it — what it means when the terms are taken seriously, where it comes from, and what work it does inside Cryptography Foundations. Read the sentence, then read it again after the sections below; it should carry more weight the second time.
Why it belongs in Signatures
Module II exists because the property that makes ownership possible. "Reading: Merkle, Secure Communications Over Insecure Channels" is one of the pillars of that module: without it, the later lessons either become memorization or lose their bite. Notice which earlier lessons this one leans on, and which later lessons will lean on it — the shape of the module is easier to see once you place this piece.
