Abstract

Steinwandt and Corona proposed a forward-secure identity-based non-interactive key distribution (ID-NIKD) scheme and proved its security, and then a forward-secure identity-based encryption (IBE) constructed from their forward-secure ID-NIKD scheme. In this study, attacks are presented to point out that their ID-NIKD scheme and IBE scheme are not forward-secure. We conclude that how to construct a forward-secure ID-NIKD scheme is still an open problem.
