_ 気になった論文：Zeroizing Without Low-Level Zeroes: New MMAP Attacks and Their Limitations, Jean-Sebastien Coron and Craig Gentry and Shai Halevi and Tancrede Lepoint and Hemanta K. Maji and Eric Miles and Mariana Raykova and Amit Sahai and Mehdi Tibouchi, http://eprint.iacr.org/2015/596

We extend the recent zeroizing attacks of Cheon, Han, Lee, Ryu and Stehle (Eurocrypt'15) on multilinear maps to settings where no encodings of zero below the maximal level are available. Some of the new attacks apply to the CLT13 scheme (resulting in a total break) while others apply to (a variant of) the GGH13 scheme (resulting in a weak-DL attack). We also note the limits of these zeroizing attacks.
