Timed-Release Hierarchical Identity-Based Encryption
Toru Oshikiri, Taiichi Saito · International Journal of Advanced Computer Science and Applications · 2014
We propose a notion of hierarchical identity-based encryption (HIBE) scheme with timed-release encryption (TRE) mechanism, timed-release hierarchical identity-based encryption (TRHIBE), and define its security models. We also show a generic construction of TRHIBE from HIBE and one-time signature, and discuss the security of the constructed scheme.
