Timed-Release Hierarchical Identity-Based Encryption

Author 1: Toru Oshikiri Author 2: Taiichi Saito

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. Read full abstract & cite →
