Abstract

By using Gap Diffie-Hellman groups, we construct an efficient ID-based signature scheme without trusted PKG for smart grid, which security relies on the hardness of the Computational Diffie-Hellman Problem (CDHP). In this scheme, PKG is prevented from forging a legal user’s signature because it only generates the partially private key. The scheme is proved to be secure against existential forgery on adaptively chosen message and ID attack, assuming CDHP is intractable. Our scheme not only satisfies security properties but also has a higher efficiency.
