Abstract

In this paper, we propose two new constructions of identity-based proxy re-encryption (IB-PRE). The most important feature of our schemes is that we no longer need the semi-trust assumption on the proxy. Moreover, we describe the IND-PrID-CCA/CPA security models for an IB-PRE in a single-hop scenario, and then give a general analysis on the relationship between the IND-PrID-CPA security model and the desirable PRE properties: unidirectionality, collusion "safeness" and non-transitivity. Our first scheme has no ciphertext expansion through the re-encryption and is proven IND-PrID-CPA secure in the random oracle model. The second one achieves the IND-PrID-CCA security.
