WebAbstract. We describe a polynomial-time cryptanalysis of the (approx-imate) multilinear map of Coron, Lepoint and Tibouchi (CLT). The attack relies on an adaptation of the so-called zeroizing attack against the Garg, Gentry and Halevi (GGH) candidate multilinear map. Zeroiz-ing is much more devastating for CLT than for GGH.
