To realize efficient instantiation from various assumptions, we next propose a generic construction of an HKIBE scheme from any plain HIBE scheme. It is based on Hanaoka et al.' ...
It provides several new and efficient instantiations since most pairing-based HIBE schemes satisfy the requirement. ...
Construction idea The basic idea is quite simple: to encrypt a message M with an identity id and time t, run the HIBE encryption algorithm Enc with M and a hierarchical identity (id, T [L−1,0] (t)) (i.e ...
