Identity-Based Cryptography on Hidden-Order Groups
Chanlgu Lin · Procedia Engineering · 2012
Recently, Saxena and Soh presented one novel cryptographic primitive based on associative one-way functions, called oracle-based group with infeasible inversion (O-GII), and it requires the order of group is hidden. In this paper, we propose three ID-based cryptographic schemes, such as ID-based non-interactive key sharing (ID-NIKS) scheme, hierarchical ID-based encryption (HIBE) scheme, and ID-based signature (IBS) scheme, based on hidden-order groups. We say that the security proof of our proposed schemes is an open problem.
