Security proof of the Schnorr Signature

cn flag

How Schnorr signature security can be proved for signature forgery, replacement, and Replay attacks?

Signatures are static, thus can be replayed. Are you thinking of the Schnorr identification protocol?

No, I am using Schnorr to sign a message m, and I want to make sure this signature can be replayed in case of a message update. i.e. sig(m) != sig(m').

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
