Abstract
In this paper, we capture forward secrecy of both PKG's master secret and user private keys, and formalize a new definition of “forward-secure ID based signature schemes with forward-secure PKG”. Then, we design a scheme and prove its security under the BDHI assumption in the standard model (without random oracles).
