Title:
Maximum Leakage Resilient IBE and IPE
Authors: Kaoru Kurosawa, Le Trieu Phong
Abstract:In this paper, we show the first identity-based encryption (IBE) scheme, and inner product encryption (IPE) scheme, both of which achieve the maximum possible leakage rate 1-o(1) in the standard model under a static assumption. Specifically, under the DLIN assumption, even if 1-o(1) fraction of each private key is arbitrarily leaked, the IBE scheme is fully secure and the IPE scheme is selectively secure. (To our knowledge, no {\it leakage resilient} IPE scheme has been known so far.)
