Abstract
-
Our first framework yields a conceptually simple and unified treatment of the KDM-secure schemes of Boneh et al. (Crypto 2008), Brakerski and Goldwasser (Crypto 2010) and Brakerski, Goldwasser and Kalai (TCC 2011) in the single-key setting.
-
Using our second framework, we obtain new dual-mode cryptosystems based on the d-linear, quadratic residuocity and decisional composite residuocity assumptions.
