Isn't IBE quite slow? And also it requires a third party for keygen and so on.

What is IBE and who said anything about it?

I was talking about EdDSA.

IBE is Identity Based Encryption, and it allows you to use your identity (name, email, etc.) as your public key.

There's nothing special about EdDSA compared to other digital signature schemes.

EDIT: Oh, I realize you were saying that ECC allows much shorter public keys than most signature schemes.
