Can we use an Identity-based signature for identity authentication?

This is clear to me that message authentication is provided by a signature scheme. Can we use an Identity-based signature for identity authentication?

What's "identity authentication", and how does it differ from "entity authentication" and "message authentication"?

I am working on the same thing. Certainly you can use an identity-based signature for authentication-- but the question is whether or not signature scheme overqualifies. Can we optimize it since we don't need message authentication but entity authentication only?

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.
