چکیده

Starting with any selectively secure identity-based encryption (IBE) scheme, we give generic constructions of fully secure IBE and selectively secure hierarchical IBE (HIBE) schemes. Our HIBE scheme allows for delegation arbitrarily many times.

HIBE with Polynomially Many Levels

We present the first hierarchical identity based encryption (HIBE) system that has full security for more than a constant number of levels. In all prior HIBE systems in the literature, the security reductions suffered from exponential degradation in the depth of the hierarchy, so these systems were only proven fully secure for identity hierarchies of constant depth. (For deep hierarchies, previ...

HIBE With Short Public Parameters Without Random Oracle

At Eurocrypt 2005, Waters presented an identity based encryption (IBE) protocol which is secure in the full model without random oracle. In this paper, we extend Waters’ IBE protocol to a hierarchical IBE (HIBE) protocol which is secure in the full model without random oracle. The only previous construction in the same setting is due to Waters. Our construction improves upon Waters’ HIBE by sig...

From Selective to Full Security: Semi-generic Transformations in the Standard Model

In this paper, we propose an efficient, standard model, semi-generic transformation of selective-secure (Hierarchical) Identity-Based Encryption schemes into fully secure ones. The main step isa procedure that uses admissible hash functions (whose existence is implied by collision-resistanthash functions) to convert any selective-secure wildcarded identity-based encryption (WIBE)<lb...

Generalization of the Selective-ID Security Model for HIBE Protocols

We generalize the selective-ID security model for HIBE by introducing two new security models. Broadly speaking, both these models allow the adversary to commit to a set of identities and in the challenge phase choose any one of the previously committed identities. Two constructions of HIBE are presented which are secure in the two models. Further, we show that the HIBEs can be modified to obta...
