Cryptanalysis of ggh map
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. In the case of Webthe GGH-NTRUSign cryptanalysis. In Section 3, we formalize the definition of a 1 There have been a variety of perturbation techniques proposed to reduce, or alter, the information leaked, see [12].

WebGGH and CLT; the Graded External Decision Di e-Hellman (GXDH) problem seems hard with CLT while it is easy for GGH. GXDH is exactly DDH for one of the components of the asymmetric graded encoding scheme. These problems have been initially used in the context of cryptographic bilinear maps [4,5,34].
