Decisional linear assumption
WebSep 8, 2015 · I had understood what does the DLIN assumption means and here is a related question. But I fail to understand the 'real hardness' in this problem. I would be grateful if someone can help me to Webdecisional linear assumption. As an instructive example, we obtain a translation of the Lewko-Waters composite order IBE scheme. This pro-vides a close analog of the Boneh-Boyen IBE scheme that is proven fully secure from the decisional linear assumption. In the full version of this paper, we also provide a translation of the Lewko-Waters unbounded
