Abstract

It is worthwhile to deal with the key-exposure problem for identity-based signature. Identity-based key-insulated signature can successfully reduce the damage caused by key-exposure, and thus attracts the researchers' great interest. In this paper, we study the problem of how to generically construct identity-based strong key-insulated signature, and proposed a generic construction of identity-based strong key-insulated signature schemes from two-level hierarchical identity-based signature.
